NOSKIP
Connect to VCC to force continuous conduction mode and sink mode.
2GNDSE
NSE
Remote ground sensing pin
3
INT
Integrator output. Short this pin to VFB pin and connect it via a capacitor to VOUT to insert the
integrator in the control loop. If the integrator is not used, short this pin to VREF.
4VSENS
E
This pin must be connected to the remote output voltage to detect overvoltage and undervoltage
conditions and to provide integrator feedback input.
5VCC
IC Supply Voltage.
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
