NCP4629x VIN VIN C1 470 n A 10 mF ceramic output decoupling capacitor is sufficient to achieve stable operation of the IC. If tantalum capacitor is used, and its ESR is high, the loop oscillation may result. The capacitor should be connected as close as possible to the output and ground pin. Larger values and lower ESR improves dynamic parameters. VOUT VOUT C2 10 m CE 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. The enable pin has an internal pull down current source. If the enable function is not needed connect CE pin to VIN. Figure 39. Typical Application Schematic When VOUT voltage could be higher than VIN voltage it is necessary to use protective diode D1. If there is possibility that VOUT voltage could be negative then it is necessary to use schottky diode D2. See Figure 40 for details. Do not force the voltage to the VOUT pin. Thermal As a power across the IC increase, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material, and also the ambient temperature affect the rate of temperature increase for the part. When the device has good thermal conductivity through the PCB the junction temperature will be relatively low in high power dissipation applications. The IC includes internal thermal shutdown circuit that stops operation of regulator, if junction temperature is higher than 160°C. After that, when junction temperature decreases below 135°C, the operation of voltage regulator would restart. While high power dissipation condition is, the regulator starts and stops repeatedly and protects itself against overheating. D1 NCP4629x VIN VIN C1 470 n CE VOUT VOUT C2 10 m GND D2 Figure 40. Typical Application Schematic with Protective Diodes PCB layout Pins number 2 and 3 must be wired to the GND plane while it is mounted on board. Make VIN and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect capacitors C1 and C2 as close as possible to the IC, and make wiring as short as possible. Input Decoupling Capacitor (C1) A 470 nF ceramic input decoupling capacitor should be connected as close as possible to the input and ground pin of the NCP4629. Higher values and lower ESR improves line transient response.
