ETA1039
5V/1.5A Output Synchronous Boost with Current Limit Setting in SOT23-6
DESCRIPTION
The ETA1039 is a high efficiency synchronous step-up converter that can provide up to 1.5A to a fixed output up to 5V from a low voltage source. Unlike most stepup 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. And ETA1039 also provides the flexibility of setting input peak current limit and thus, output current is limited.
