FP6288
Non-Synchronous PWM Boost Converter
FP6288
General Description
The FP6288 is a boost topology switching regulator for wide operating voltage applications. Its
built-in 20 mΩ power MOSFET makes this regulator highly power efficient. The non-inverting input of
error amplifier connects to a 0.6V precision reference voltage. The FP6288 has internal soft start and
programmable over current protection set by external resistor.
The FP6288 is available in the small footprint SOP-8L(EP) package to fit in space-saving PCB
layout for miscellaneous application fields.
Features
Wide Supply Voltage Operating Range: 2.4 to 5.5V
Precision Feedback Reference Voltage: 0.6V (±2%)
Shutdown Current: <1μA
Internal Fixed PWM frequency: 350KHz
Internal Soft Start Function :7ms (SS)
Over Current Protection Function (OCP)
Over Voltage Protection
Package: SOP-8L(EP)
Duty Cycle: PWM Switching Control Circuit (15%~90%)
