The FR9811 is a synchronous step-down DC/DC converter with fast constant on time (FCOT) mode control. The device provides 4.5V to 23V input voltage range and 2A continuous load current capability. It is constant on time pulse width modulation (PWM) controller that supports FCOT mode control. Operation frequency depends on Input and output voltage condition.
The FR9811 fault protection includes cycle-by-cycle current limit, short circuit protection, UVLO and thermal shutdown. The soft-start function prevents inrush current at turn-on. The FR9811 use fast
constant on time control that provides fast transient response, the noise immunity and all kinds of very low ESR output capacitor for ensuring performance stabilization.
The FR9811 is offered in SOT-23-6 package, which provides good thermal conductance.
