PIN FUNCTION
N° Name Description
1 NOSKIP Connect to V
CC
to force continuous conduction mode and sink mode.
2 GNDSE
NSE
Remote ground sensing pin
3 INT Integrator output. Short this pin to VFB pin and connect it via a capacitor to V
OUT
to insert the
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.
5V
CC
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
