General Description

The GS5801 is a high efficiency synchronous step-up converter that can provide up to 3W of power to a boosted output from a low voltage source.

Unlike most step-up converter, not only it starts up at a very low input voltage as low as 0.85V, it also 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.
