Description
Power Source Input. VIN is the source of the pFET high-side switch. Bypass VIN to GND with a 4.7 μF or greater
capacitor as close to the ADP2147 as possible.
Switch Node Output. SW is the drain of the P-channel MOSFET switch and N-channel synchronous rectifier.
Connect the output LC filter between SW and the output voltage.
Ground. Connect the input and output capacitors to GND.
Buck Activation. To turn on the buck, set EN to high. To turn off the buck, set EN to low.
Voltage Select Input for Simple Dynamic Voltage Scaling (DVS). Drive VSEL low to switch the VOUT pin to the
default voltage setting. Drive VSEL high to switch VOUT to the alternate voltage setting.
Output Voltage Sensing Input.
