PIN CONFIGURATION (TOP VIEW)
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 re-
settable OVP(over voltage protection)circuit.
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 current............................................100μA 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-drive current of MOS FET.
14-pin DIP,16-pin SOP 1.5W(at 25°C)
Simplified peripheral circuit with protection circuit and built-in
large-capacity totempole output
High-speed current limiting circuit using pulse-by-pulse
method(CLM+pin)
Over-voltage protection circuit with an externally re-settable
latch(OVP)
Protection circuit for output miss action at low supply
voltage(UVLO)
High-performance and highly functional power supply
Triangular wave oscillator for easy dead time setting
SOFT start function by expanding period
APPLICATION
Feed forward regulator,fly-back regulator
