NCP4623 APPLICATION INFORMATION A typical application circuits for NCP4623 series is of voltage divider low enough to achieve cross current shown in Figure 49. around 2 (cid:2)A to eliminate error. Output voltage can be computed from the equation: NCP4623x (cid:3) (cid:5) VIN VOUT R1 VIN VOUT VOUT(cid:2)2.5 1(cid:4)R2 (cid:4)R1(cid:6)IADJ (eq. 1) C1 C2 CE 100n 100n GND Enable Operation The enable pin CE may be used for turning the regulator on and off. The IC is switched on when a high level voltage is applied to the CE pin. Do not leave the CE pin unconnected or between VCEH and VCEL voltage levels as NCP4623xADJ this may leave the output voltage unstable or cause indefinite VIN VOUT VIN VOUT and unexpected currents flows internally. R1 C1 C2 100n CE ADJ 100n Current Limit GND R2 This regulator includes a fold−back type current limit circuit. This type of protection doesn’t limit output current up to specified current capability in normal operation, but when an over current occurs, output voltage and current decrease until the over current condition ends. Typical Figure 49. Typical Application Schematics characteristics of this protection type can be observed in the Output Voltage vs. Output Current graphs shown in the typical characteristics section of this datasheet. Input Decoupling Capacitor (C1) A 0.1 (cid:2)F ceramic input decoupling capacitor should be Thermal connected as close as possible to the input and ground pin of As power across the IC increase, it might become the NCP4623. Higher values and lower ESR improves line necessary to provide some thermal relief. The maximum transient response. power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration Output Decoupling Capacitor (C2) on the PCB, the board material, and also the ambient Recommended values of the ceramic output decoupling temperature affect the rate of temperature increase for the capacitor is in the range from 0.1 (cid:2)F to 2.2 (cid:2)F. Stable part. When the device has good thermal conductivity operation of the regulator should be achieved within this through the PCB the junction temperature will be relatively range. If a tantalum capacitor is used, and its ESR is high, low in high power dissipation applications. loop oscillation may result.

Connect capacitors C1 and C2 as close as possible to cause an error in V , therefore it is good to choose values OUT the IC, and make wiring as short as possible. www.onsemi.com 16
