Description
Feedback input pin of the Error Amplifier. Connect a resistor divider from the converter ’s output
voltage to this pin to set the converter ’s output voltage.
Ground pin. Connect to thermal pad.
The drains of the internal MOSFETs. The output inductor should be connected to this pin.
Power input for the power stage
Input supply pin for internal bias circuitry. A 0.1 m F ceramic bypass capacitor is preferred to connect
to this pin.
No connection for NCP1595 or NCP1595C
Logic input to enable the part. Logic high to turn on the part and logic low to shut off the part.
An internal pullup forces the part into an enable state when no external bias is present on the pin.
For NCP1595A only
Exposed pad of the package provides both electrical contact to the ground and good thermal contact
to the PCB. This pad must be soldered to the PCB for proper operation.
