仕様・特性

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 PIN CONFIGURATION (TOP VIEW) supply. This IC can directly drive the MOS-FET with fast rise and fast fall COLLECTOR 1 16 Vcc VOUT 2 15 CLM+ EMITTER 3 14 CLM- VF 4 13 GND ON/OFF 5 12 CT It has another big feature of current protection to short and over OVP 6 11 T-OFF current,owing to the integrated timer-type protection circuit,if few DET 7 10 CF F/B 8 9 T-ON 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. parts are added to the primary side. The M51995A is equivalent to the M51977 with externally re- Outline 16P4 settable OVP(over voltage protection)circuit. FEATURES COLLECTOR Vcc 19 CLM+ 3 18 CLM- VF 4 17 GND 5 16 6 •Modified totempole output method with small through current 20 2 EMITTER •Output rise time 60ns,fall time 40ns 1 VOUT 500kHz operation to MOS FET •Output current...............................................................±2A 15 ON/OFF 7 14 CT Compact and light-weight power supply HEAT SINK PIN •Small start-up current............................................90µA typ. •Big difference between "start-up voltage" and "stop voltage" makes the smoothing capacitor of the power input section small.
