The AS1002 is a buck topology of switching regulator for wide operating voltage applications field. The AS1002 includes a high current P-channel MOSFET, high precision reference (0.5V) for comparing output voltage with feedback amplifier, an internal dead-time control and oscillator for controlling the maximum duty cycle and PWM frequency, and has power-on programmable soft start time and short circuit PMOS turn-off and auto re-start protection functions.
The AS1002 is available in a low profile SOP-8L package.
