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 resettable 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
