Utsource electronic components FDPF7N50U


Utsource electronic components FDPF7N50U picture 1.Description
U51995A Is the primary switching regulator controller which l 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 last switciWng 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.
2.Features
500kHz operation to MOS FET‘Output rise time 6Ons.f all time 4Ons
Modified totempole output method with small through current
Compact and light-weight power supply
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 IOV
