NCP4688 APPLICATION INFORMATION A typical application circuit for NCP4688 series is shown Enable Operation in the Figure 41. The enable pin CE may be used for turning the regulator on and off. The IC is switched on when a high level voltage NCP4688x is applied to the CE pin. The enable pin has an internal pull VIN VOUT down current source which assure off state of LDO in case VIN VOUT the CE pin will stay floating. If the enable function is not C1 CE C2 needed connect CE pin to V . 1.0 (cid:2)F GND 1.0 (cid:2)F IN The D version of the NCP4688 device includes a transistor between V and GND that is used for faster OUT discharging of the output capacitor. This function is activated when the IC goes into disable mode. Figure 41. Typical Application Schematic Thermal Consideration As a power across the IC increase, it might become necessary to provide some thermal relief. The maximum Input Decoupling Capacitor (C1) power dissipation supported by the device is dependent A 1.0 (cid:2)F ceramic input decoupling capacitor should be upon board design and layout. Mounting pad configuration connected as close as possible to the input and ground pin of on the PCB, the board material, and also the ambient the NCP4688 device. Higher values and lower ESR temperature affect the rate of temperature increase for the improves line transient response. part. When the device has good thermal conductivity Output Decoupling Capacitor (C2) through the PCB the junction temperature will be relatively A 1.0 (cid:2)F ceramic output decoupling capacitor is sufficient low in high power dissipation applications. to achieve stable operation of the device.
