FP6112 320KHz, 3A Asynchronous Buck Regulator
General Description
Download
    The FP6112 is a wide input range buck switching regulator suitable for most applications. The FP6112 includes a high current P-MOSFET, a high precision reference (0.8V) for comparing output voltage with a feedback amplifier, an internal soft start timer and dead-time controller. The oscillator controls both the maximum duty cycle and PWM frequency.


Features
˙Precision Feedback Reference Voltage: 0.8V (2%)
˙Wide Supply Voltage Operating Range: 3.6 to 25V
˙Low Current Consumption: 3mA
˙Internal Fixed Oscillator Frequency: 320KHz (Typ.)
˙Internal Soft-Start Function (SS)
˙Built-In P-MOSFET for 3A Output Loading
˙Over Current Protection
˙Package: SOP-8L
