M51995P DIP16 SWITCHING REGULATOR CONTROL (14816)
FEATURES 500kHz operation to MOS FET •Output current...............................................................±2A •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............................................90μA 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. 16-pin DIP,20-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(Two system of CLM+pin,CLM-pin) •Protection by intermittent operation of output over current......Timer protection circuit •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
APPLICATION Feed forward regulator,fly-back regulator
RECOMMENDED OPERATING CONDITIONS Supply voltage range............................................12 to 36V Operating frequency.................................less than 500kHz Oscillator frequency setting resistance •T-ON pin resistance RON...........................10k to 75kW •T-OFF pin resistance ROFF..........................2k to 30kW
