Description
Power Ground for power, analog blocks. Must be connected to the system ground.
Switch Power pin connects power transistors to one end of the inductor.
Analog Ground analog and digital blocks. Must be connected to the system ground.
Feedback Voltage from the buck converter output. This is the input to the error amplifier. This pin is
connected to the resistor divider network between the output and AGND.
Enable of the IC. High level at this pin enables the device. Low level at this pin disables the device.
PG pin is for NCP6354 with Power Good option. It is open drain output. Low level at this pin
indicates the device is not in power good, while high impedance at this pin indicates the device is
in power good.
Analog Supply. This pin is the analog and the digital supply of the device. An optional 1 mF or
larger ceramic capacitor bypasses this input to the ground. This capacitor should be placed as
close as possible to this input.

Power Supply Input. This pin is the power supply of the device. A 10 mF or larger ceramic capacitor
must bypass this input to the ground. This capacitor should be placed as close a possible to this
input.
Exposed Pad. Must be soldered to system ground to achieve power dissipation performances.
This pin is internally unconnected
