ncp4620 http://onsemi.com 13 application information a typical application circuit for ncp4620 series is shown in figure 38. vin vout ce gnd c1 c 2 1 1 vin vout ncp4620x figure 38. typical application schematic input decoupling capacitor (c1) a 1 f ceramic input decoupling capacitor should be connected as close as possible to the input and ground pin of the ncp4620. higher values and lower esr improves line transient response. output decoupling capacitor (c2) a 1 f ceramic output decoupling capacitor is enough to achieve stable operation of the ic. if a tantalum capacitor is used, and its esr is high, loop oscillation may result. the capacitors should be connected as close as possible to the output and ground pins. larger values and lower esr improves dynamic parameters. 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. output discharger the d version includes a transistor between vout and gnd that is used for faster discharging of the output capacitor. this function is activated when the ic goes into disable mode. 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 t he pcb the junction temperature will be relatively low in high power dissipation applications. pcb layout make the vin and gnd line as large as practical. 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.
