Product Summary

The m51995afp is a prinary switching regulator controller which is especially designed to get the regulated DC voltage from AC power supply. The m51995afp can directly drive the MOS-FET with fast rise and fast fall output pulse. The m51995afp has the functions of not only high frequency OSC and fast output drive but also current limit with fast response and high sensibility.

Parametrics

m51995afp absolute maximum ratings: (1) supply voltage Vcc: 36V; (2) collector voltage Vc: 36V; (3) output current Io: ±2A (Peak) , ±0.15S (continuous) ; (4) VF terminal voltage VVF: Vcc; (5) CLM-terminal voltage: -4 to +4V; (6) DET terminal voltage: 8mA; (7) Power dissipation Pd: 1.5W (Ta=25°C) ; (8) Operating temperature: -30 to +85°C; (9) Storage temperature: -30 to +85°C; (10) Junction temperature Tj: 150°C.

Features

m51995afp features: (1) 500kHz operation to MOS FET; (2) output current: ±2A; (3) output rise time 60ns, fall time 40ns; (4) modified totempole output method with small through current; (5) compact and light-weight power supply; (6) small start-up current: 90μA; (7) protection circuit for output miss action at low supply voltage (UVLO) ; (8) high-performance and highly functional power supply.
