FP6102

FP6102 20V, 3A Buck Switching Regulator General Description The FP6102 is a buck switching regulator for wide operating voltage application fields. The FP6102 includes a high current P-MOSFET, high precision reference (0.5V) for comparing output voltage with a feedback amplifier, an internal dead-time controller and oscillator for controlling the maximum duty cycle and PWM frequency. It also has power-on programmable soft start time, short circuit PMOS turn-off and auto re-start protection functions.
