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 NCP6334B 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.
MODE pin is for NCP6334C with mode external selection option. High level at this pin forces the
device to operate in forced PWM mode. Low level at this pin enables the device to operate in
automatic PFM/PWM mode for power saving function.

Analog Supply. This pin is the analog and the digital supply of the device. An optional 1 mF or lar-
ger 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 capacit-
or 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
