20V, 2A Buck Switching Regulator
FP6101
General Description
The FP6101 is a buck switching regulator for wide operating voltage application fields. The
FP6101 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.
Features
Precision Feedback Reference Voltage: 0.5V (2%)
Wide Supply Voltage Operating Range: 3.6 to 20V
Low Current Consumption: 3mA
Internal Fixed Oscillator Frequency: 340KHz (Typ.)
Internal Soft-Start Function (SS)
Short Circuit Shutdown and Auto Re-start function (ARSCP)
Built-in P-MOSFET for 2A Loading Capability
Over Current Protection
Package: SOP-8L
