FP6312F
Production
High Efficiency 5.5V 2A Synchronous Step Down Converter
The FP6312F is a high efficiency, high frequency and pulse width modulation (PWM) synchronous DC-DC step-down converter. The 100% duty cycle feature provides low dropout operation, extending battery life in portable systems.
The internal synchronous switch increases efficiency and eliminates the need for external Schottky diode. At shutdown mode, the input supply current is less than 0.85µA. The FP6312F use the constant on time control scheme that provides fast transient response, the noise immunity and all kinds of very low ESR output capacitor for ensuring performance stabilization.
The FP6312F fault protection includes over current protection, short circuit protection, UVLO and thermal shutdown. The Internal soft-start function prevents inrush current at turn-on.
The FP6312F is offered in SOT-563-6L/SOT-23-5L/ SOT-23-6L Packages.
