HA16666P

HA16666P/FP 600kHz PWM Controlled Switching Regulator Description The HA16666P/FP is a voltage mode PWM (pulse width modulation) control IC for switching regulator control. It can drive a power MOS FET efficiently on 600 kHz. Its stanby current is 0.3 mA (max), and it is used as the primary control power supply. Functions +5 V reference voltage circuit Triangular waveform oscillator PWM comparator Output circuit (Totem pole output) Overcurrent protection circuit (with one-pulselatch mode) Undervoltage lockout protectoin circuit Soft start and quick shutdown function Remote control function Comparator with internal 1.3 V reference voltage Features High-speed switching; tr = 80 ns (15 V amplitude) tf = 40 ns (15 V amplitude) Low power dissipation; 0.3 mA max in standby state 12 mA max in operation state (V IN = 15 V) Dual-slope highly accurate dead-band duty setup circuit; Setup accuracy Du = ±3% (max) Wide output pulse width control range; 0 to 75% HA16666P/FP Undervoltage lockout protection; VIN high threshold voltage 10 V typ VIN low threshold voltage 8 V typ Two input threshold voltage for overcurrent protection cmparator; fixed voltage (1.3 V) variable voltage Double pulse output protection by overcurrent protection circuit with one-pulse latch mode Wide input supply voltage range; VCC = 11 to 40 V Ordering Information Type HA16666P HA16666FP Package DP-16 FP-16DA 2 HA16666P/FP Pin Arrangement E/I ST CT RT1 RT2 OSC Out GND N.C 1 2...
