NCP81234 Datasheet (ON Semiconductor) - Dual-Channel/Two-Phase Controller

NCP81234, Dual-Channel/Two-Phase Controller

Pin Name Type Description 1 VIN Power Input Power Supply Input.

Power supply input pin of the device, which is connected to the integrated 5 V LDO.

4.7 mF or more ceramic capacitors must bypass this input to power ground.

The capac- itors should be placed as close as possible to this pin.
