FP6276B-5V/2.1A移动电源应用同步升压IC

FP6276B-500kHz 5A High Efficiency Synchronous PWM Boost Converter

General Description
      The FP6276B is a current mode synchronous boost DC-DC converter with PWM/PSM control. Its PWM circuitry with built-in 50mΩ high side switch and 50mΩ low side switch 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.
