Description:
The SR1470A is a synchronous step-down regulator with an internal power MOSFET. The SR1470A achieves 2A a of 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. Hiccup protection, the cycle-by-cycle over current limit and thermal shutdown. Soft-start function reduces the stress
on the input source at startup. The SR1470A requires a minimal number of readily available external components, providing a compact solution.
