MP110 – 900V OFFLINE SWITCHING REGULATOR

on, the IC implements leading-edge blanking.

During the blanking time, any trigger signal on

source pin is blocked. An internal leading-edge

blanking(LEB) unit containing two LEB times is

employed between the Source pin and the

current comparator input to avoid premature

switching pulse termination due to the parasitic

capacitances. During the blanking time, the

current comparator is disabled and can not turn

off the MOSFET.

Current sensor leading edge blanking inhibits the

typical value) and SCP leading edge blanking

inhibits the SCP current comparator during 600ns

current sense waveform and the leading edge

blanking.
