FP6151XR-G1

FP6151 5A, 36V, Step-Down Converter General Description The FP6151 is a buck regulator with a built in internal power MOSFET. It achieves 5A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. A wide switching frequency range allows efficiency and external component size to be optimized. The device includes under voltage lockout and thermal shutdown protection. The regulator only consumes 10µA supply current in shutdown mode. The FP6151 requires a minimum number of readily available external components to complete a 5A buck regulator solution.
