320KHz, 3A Asynchronous Buck Regulator
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.
Precision Feedback Reference Voltage: 0.8V (2%)
Wide Supply Voltage Operating Range: 3.6 to 20V
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
