Product Summary

The FP6102DR-LF is a buck switching regulator for wide operating voltage application fields. The FP6102DR-LF 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.
