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.
