M51996FP - SWITCHING REGULATOR CONTROL

Datasheet Summary

Description

M51996A 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 and with a large-drive totempole output.

Features

  • 500kHz operation to MOS FET Output current±1A Output rise time 60ns,fall time 40ns Modified totempole output method with small through current Compact and light-weight power supply.
  • Small start-up current100µA 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 generated by the gate-dri.

MITSUBISHI (Dig./Ana. INTERFACE) M51996AP/FP SWITCHING REGULATOR CONTROL DESCRIPTION M51996A 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 and with a large-drive totempole output. Type M51996A 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. The M51996A is equivalent to the M51978 with externally resettable OVP(over voltage protection)circuit.
