ETA1136S2F

The ETA1136 is a high efficiency synchronous step-up converter that can provide up to 1.5A to a fixed 5V output from a low voltage source. Unlike most step-up converter, it incorporates circuits that disconnect the input from output, during shutdown, short-circuit, output current overloading, or other events when output is higher than the input. This eliminates the need for an external MOSFET and its control circuitry to disconnect the input from output, and provides robust output overload protection.
