FP6291 DC/DC 升压IC：The FP6291 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.25 Ω

power MOSFET make this regulator highly power efficient. The internal compensation network also

minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects

to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current.

The FP6291 is available in the SOT23-6L package and provides space-saving PCB for the application fields.
