M51995FP - SWITCHING REGULATOR CONTROL

Datasheet Summary

Description

M51995A is the primary switching regulator controller which is especially designed to get the regulated DC voltage from AC power supply.

This IC can directly drive the MOS-FET with fast rise and fast fall output pulse.

Features

500kHz operation to MOS FET.
Output current±2A.
Output rise time 60ns,fall time 40ns.
Modified totempole output method with small through current Compact and light-weight power supply.
Small start-up current90µA typ.
Big difference between "start-up voltage" and "stop voltage" makes the smoothing capacitor of the power input section small. Start-up threshold 16V,stop voltage 10V.
Packages with high power dissipation are used to with-stand the heat.

MITSUBISHI (Dig./Ana. INTERFACE) M51995AP/FP SWITCHING REGULATOR CONTROL DESCRIPTION M51995A is the primary switching regulator controller which is especially designed to get the regulated DC voltage from AC power supply. This IC can directly drive the MOS-FET with fast rise and fast fall output pulse. Type M51995A has the functions of not only high frequency OSC and fast output drive but also current limit with fast response and high sensibility so the true "fast switching regulator" can be realized. It has another big feature of current protection to short and over current,owing to the integrated timer-type protection circuit,if few parts are added to the primary side. The M51995A is equivalent to the M51977 with externally resettable OVP(over voltage protection)circuit.
