The converter operates at a regulated 5.5- MHz frequency pulse width modulation (PWM) at moderate to heavy load currents. At light load currents, the TPS8267xconverteroperatesinpower-savemodewithpulsefrequencymodulation(PFM). The converter uses a unique frequency-locked ring-oscillating modulator to achieve best-in-class load and line response. One key advantage of the non-linear architecture is that there is no traditional feed-back loop. The loop response to change in V is essentially instantaneous, which explains the transient response. Although this O type of operation normally results in a switching frequency that varies with input voltage and load current, an internal frequency lock loop (FLL) holds the switching frequency constant over a large range of operating conditions. Combined with best-in-class load and line-transient response characteristics, the low quiescent current of the device (approximately 17μA) helps to maintain high efficiency at light load while that current preserves a fast transientresponseforapplicationsthatrequiretightoutputregulation.

During power-save mode, the converter operates in discontinuous current, (DCM) single-pulse PFM mode, which produces a low output ripplecomparedwithotherPFMarchitectures. When in power-save mode, the converter resumes its operation when the output voltage falls below the nominal voltage. The converter ramps up the output voltage with a minimum of one pulse and goes into power-save modewhentheoutputvoltageiswithinitsregulationlimits. The IC exits PFM mode and enters PWM mode when the output current can no longer be supported in PFM mode. As a consequence, the DC output voltage is typically positioned approximately 0.5% above the nominal outputvoltage.ThetransitionbetweenPFMandPWMisseamless. PFM Mode at Light Load PFM Ripple Nominal DC Output Voltage PWM Mode at Heavy Load Figure7. OperationInPFMModeAndTransferToPWMMode 9.3.2 ModeSelection The MODE pin selects the operating mode of the device. Connecting the MODE pin to GND enables the automatic PWM and power-save mode operation. The converter operates in regulated frequency PWM mode at moderate to heavy loads, and operates in PFM mode during light loads. This type of operation maintains high efficiencyoverawideloadcurrentrange. Pulling the MODE pin high forces the converter to operate in PWM mode even at light-load currents. The advantage is that the converter modulates its switching frequency according to a spread spectrum PWM modulationtechniquethatallowssimplefilteringoftheswitchingharmonicsinnoise-sensitiveapplications.Inthis mode,theefficiencyislowerwhencomparedtothepower-savemodeduringlightloads. For additional flexibility, it is possible to switch from power-save mode to PWM mode during operation. This type ofoperationallowsefficientpowermanagementbyadjustingtheoperationoftheconvertertothespecificsystem requirements. 9.3.3 SpreadSpectrum,PWMFrequencyDithering The goal of spread spectrum architecture is to spread out the emitted RF energy over a larger frequency range so that any resulting electromagnetic interference (EMI) is similar to white noise. The end result is a spectrum that is continuous and lower in peak amplitude. Spread spectrum makes it easier to comply with EMI standards. It also makes it easier to comply with the power supply ripple requirements in cellular and non-cellular wireless applications. Radio receivers are typically susceptible to narrowband noise that is focused on specific frequencies. Switching regulators can be particularly troublesome in applications where electromagnetic interference (EMI) is a concern. Switching regulators operate on a cycle-by-cycle basis to transfer power to an output. In most cases, the frequency of operation is either fixed or regulated, based on the output load. This method of conversion creates large components of noise at the frequency of operation (fundamental) and multiples of the operating frequency(harmonics). 10 SubmitDocumentationFeedback Copyright©2010–2016,TexasInstrumentsIncorporated ProductFolderLinks:TPS82670 TPS82671 TPS82672 TPS82673 TPS82674 TPS82675 TPS82676TPS82677 TPS826711 TPS826716 TPS826721 TPS826745 TPS826765 TPS8267195

Pulling the EN pin low forces the device into shutdown. In this mode, all internal circuits are turned off and the V currentreducestothedeviceleakagecurrent,whichistypicallyafewhundrednanoamps. IN The TPS8267x device can actively discharge the output capacitor when it turns off. The integrated discharge resistor has a typical resistance of 100 Ω. The required time to ramp down the output voltage depends on the loadcurrentandthecapacitancepresentattheoutputnode. 9.4.2 SoftStart The TPS8267x has an internal soft-start circuit that limits the in-rush current during start-up. This circuit limits input voltage drop when a battery or a high-impedance power source is connected to the input of the MicroSiP™ DC/DCconverter. The soft-start system progressively increases the switching on-time from a minimum pulse-width of 35ns as a function of the output voltage. This mode of operation continues for approximately 100μs after the enable. If the outputvoltagedoesnotreachitstargetvaluewithinthesoft-starttime,thesoft-starttransitionstoasecondmode ofoperation. If the output voltage rises above approximately 0.5V, the converter increases the input current limit and thus enables the power supply to come up properly. The start-up time mainly depends on the capacitance present at theoutputnodeandtheloadcurrent. 12 SubmitDocumentationFeedback Copyright©2010–2016,TexasInstrumentsIncorporated ProductFolderLinks:TPS82670 TPS82671 TPS82672 TPS82673 TPS82674 TPS82675 TPS82676TPS82677 TPS826711 TPS826716 TPS826721 TPS826745 TPS826765 TPS8267195

For most applications, the input capacitor that is integrated into the TPS8267x should be sufficient. If the application exhibits a noisy or erratic switching frequency, experiment with additional input ceramic capacitance tofindaremedy. The TPS8267x uses a tiny ceramic input capacitor. When a ceramic capacitor is combined with trace or cable inductance, such as from a wall adapter, a load step at the output can induce ringing at the VIN pin. This ringing can couple to the output and be mistaken as loop instability or can even damage the part. In this circumstance, additional "bulk" capacitance, such as electrolytic or tantalum, should be placed between the input of the converter and the power source lead to reduce ringing that can occur between the inductance of the power sourceleadsandC.

At light loads, the output capacitor limits the output ripple voltage and provides holdup duringlargeloadtransitions. The TPS8267x is designed as a Point-Of-Load (POL) regulator, to operate stand-alone without requiring any additional capacitance. Adding a 2.2μF ceramic output capacitor (X7R or X5R dielectric) generally works from a converterstabilitypointofview,butdoesnotnecessarilyhelptominimizetheoutputripplevoltage. For best operation (i.e. optimum efficiency over the entire load current range, proper PFM/PWM auto transition), the TPS8267xSIP requires a minimum output ripple voltage in PFM mode. The typical output voltage ripple is ca. 1% of the nominal output voltage V . The PFM pulses are time controlled resulting in a PFM output voltage O ripple and PFM frequency that depends (first order) on the capacitance seen at the MicroSiPTM DC/DC converter'soutput. In applications requiring additional output bypass capacitors located close to the load, care should be taken to ensure proper operation. If the converter exhibits marginal stability or erratic switching frequency, experiment withadditionallowvalueseriesresistance(e.g.50to100mΩ)intheoutputpathtofindaremedy. Because the damping factor in the output path is directly related to several resistive parameters (e.g. inductor DCR, power-stage r , PWB DC resistance, load switches r …) that are temperature dependant, the DS(on) DS(on) converter small and large signal behavior must be checked over the input voltage range, load current range and temperaturerange.
