RS2051N

Novel Low Cost Green-Mode PWM Controller with Soft Start & Latch Mode

Orister Corporation 

Page No. : 8/13

Latch Mode

In some applications, latch operation for SCP&OLP may be necessary. The RS2051 offer this function. When the output is OLP

or SCP, the RS2051 could cut off GATE output and pull down VDD voltage immediately, and enter Latch Mode. To restart the

power supply, it is necessary to disconnect the AC line voltage of the power supply.

GATE Driver & Soft Clamped

The RS2051’ output designs a totem pole to drive a periphery power MOSFET. The dead time is introduced to minimize the

transfixion current during the output operating. The novel soft clamp technology is introduced to protect the periphery power

MOSFET from breaking down and current saturation of the Zener.
