FP6115
340KHz, 2A, Asynchronous Step-Down Regulator
General Description
The FP6115 is a buck switching regulator for wide operating voltage application fields. The
FP6115 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 is
for controlling the maximum duty cycle and PWM frequency.
Features
Precision Feedback Reference Voltage: 0.8V (2%)
Wide Supply Voltage Operating Range: 3.6 to 23V
Output Adjustable From 0.8V to 16V
Low Current Consumption: 3mA
Internal Fixed Oscillator Frequency: 340KHz (Typ.)
Internal Soft-Start Function (SS)
Built-In P-MOSFET for 2A Output Loading
