fr9207
production
18v, 4a synchronous step-down dc/dc converter
applications
the fr9207 is a synchronous step-down dc/dc converter. the device provides 4.5v to 18v input voltage range and 4a continuous load current capability. operation frequency depends on input and output voltage condition. at light load condition, the fr9207 can operate at power saving mode to support high efficiency and reduce power loss.
the fr9207 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 fr9207 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 fr9207 is offered in tsot-23-6 package, which provides good thermal conductance.
