TPS60300,TPS60301,TPS60302,TPS60303 www.ti.com SLVS302B–DECEMBER2000–REVISEDOCTOBER2015 9 Detailed Description 9.1 Overview The TPS6030x charge pumps are voltage quadruplers that provide a regulated 3.3-V or 3-V output from a 0.9-V to 1.8-V input. They deliver a maximum load current of 20 mA. Designed specifically for space critical battery powered applications, the complete converter requires only five external capacitors and enables the design to use low-cost, small-sized, 1-µF ceramic capacitors. The TPS6030x circuits consist of an oscillator, a voltage reference, an internal resistive feedback circuit, an error amplifier, two charge pump stages with MOSFETswitches,ashutdownandstart-upcircuit,andacontrolcircuit. 9.2 Functional Block Diagram Copyright©2000–2015,TexasInstrumentsIncorporated SubmitDocumentationFeedback 9 ProductFolderLinks:TPS60300 TPS60301 TPS60302 TPS60303

TPS60300,TPS60301,TPS60302,TPS60303 SLVS302B–DECEMBER2000–REVISEDOCTOBER2015 www.ti.com 9.3 Feature Description 9.3.1 Power-GoodDetector The power-good output is an open-drain output on the TPS60300 and TPS60301 or a push-pull output on the TPS60302 and TPS60303. The PG-output pulls low when the output of OUT2 is out of regulation. When the output rises to within 98% of regulation, the power-good output goes active high. In shutdown, power-good is pulled low. In normal operation, an external pullup resistor with the TPS60300 and TPS60301 is typically used to connect the PG pin to V . The resistor should be in the 100-kΩ to 1-MΩ range. If the PG output is not used, it OUT should remain unconnected. Output current at PG (TPS60302, TPS60303) will reduce maximum output current atOUT2. 9.4 Device Functional Modes 9.4.1 Start-upProcedure The device is enabled when EN is set from logic low to logic high. CP1 will first enter a DC start-up mode during which the capacitor on OUT1 is charged up to about V . After that, it starts switching to boost the voltage further IN up to about two times V . CP2 will then follow and charge up the capacitor on OUT2 to about the voltage on IN OUT1,afterthat,itwillalsostartswitchingandboostupthevoltagetoitsnominalvalue.ENmustnotexceedthe highestvoltageappliedtothedevice. NOTE Duringstart-upwithV =0V,thehighestvoltageistheinputvoltage. OUT 9.4.2 Shutdown Driving EN low disables the converter. This disables all internal circuits, reducing input current to only 0.05 µA. Leakage current drawn from the output pins OUT1 and OUT2 is a maximum of 1 µA. The device exits shutdown once EN is set high (see Start-up Procedure). The typical no-load, start-up time is 400 µs. When the device is disabled, the load is isolated from the input. This is an important feature in battery operated products because it extendsthebatteryshelflife. 10 SubmitDocumentationFeedback Copyright©2000–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS60300 TPS60301 TPS60302 TPS60303

Forthemaximumoutputcurrentandbestperformance,fiveceramiccapacitorswithaminimumvalueof1 µFare recommended. This value is necessary to assure a stable operation of the system due to the linear mode. For lower currents or higher allowed output voltage ripple, other capacitors can be used. With flying capacitors lower than1µF,themaximumoutputpowerwilldecrease.Thismeans that the device will work in the linear mode with loweroutputcurrents. Theinputcapacitorimprovessystemefficiencybyreducingtheinputimpedanceandstabilizingtheinputcurrent.

The output currents of the input power supply must be rated according to the supply voltage, output voltage, and output current of the TPS6030x. 12 Layout 12.1 Layout Guidelines All capacitors must be soldered as close as possible to the IC. A PCB layout proposal for a two-layer board is shown in Figure 24. Care has been taken to connect all capacitors as close as possible to the circuit to achieve optimized output voltage ripple performance. The bottom layer is not shown in Figure 24. It only consists of a ground-planewithasingletrackbetweenthetwoviasthatcanbeseenintheleftpartofthetoplayer. 12.2 Layout Example Figure24.
