M51977P Product Details

Mitsubishi IC type M51977P, FP are the off-ine primary .PWM controller which are especially designed for SMPS toget the regulated DC voltage from AC power supply.
As the totempole type high power-driver-circuit is inte-grated in these IC. these IC can drive the MOS-FET withtast rise and fast fall output pulse.
Type M51977P, FP have the functions of not only high fre-quency OSC and fast output drive but also current limit withfast response and high sensibility so the true "fast switchingregurator" can be realized.

They have another big features of current protection toshort and over current at secondary side, owing to the inte-grated timer type protection-circuit if few parts are addedto the primary circuit.


FEATURE
Type M51977P. FP are the powerful and unique one so theSMPS with M51977P, FP will be able to realize such the fe-atures as:

.500 kHz operation of MOS-FET.
 · Output current of +2A
 · Fast rise time of 60ns and fast fall time of 40ns
 · Small through current owing to "modified totempoledriver circuit.'
. Compact and light-weight power supply
  . Small start-up current·  80uA typ.

  · Big difference between "start-up voltage" and "stopvoltage" 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-drive current ofMOS FET
    16-pin DIP, 20-pin SOP 1.5W (at 25C)
. Simplified peripheral circuit with protection circuit and built-in large capacity totempole output
  . High-speed current limiting circuit using puise-by-pulse method (Two systems of CLM+pin, CLM- pin)

  Protection by intermittent operation of output over current--Timer protection circuit

  . Over-voltage protection circuit (OVP)
  . Protection circuit for output miss action at low supplyvoltage (UVLO)
. High-performance and highly functional power supply

  · Triangular wave oscillator for easy dead time setting

APPLICATION
Feed lorward regulator, Fly back regulator
