NSE

Remote ground sensing pin

3

INT

integrator in the control loop. If the integrator is not used, short this pin to VREF.

4

VSENS

E

This pin must be connected to the remote output voltage to detect overvoltage and undervoltage

conditions and to provide integrator feedback input.

Supply voltage for IC core. Connect to 5V bus.

6

GND

Signal ground

7

VREF

0.9 V voltage reference. Connect max. a 10nF ceramic capacitor between this pin and ground.

This pin is capable to source or sink up to 250uA
