ETA1039数据手册ETA中文资料规格书

描述 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. 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.
