ETA1043
14V Synchronous Boost with True Shutoff with Selectable CV and CC Output
DESCRIPTION
The ETA1043 is a high efficiency synchronous step-up converter that can provide at least 100mA to a boosted output up to 14V 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.
A switching frequency of 1.2MHZ minimizes solution footprint by allowing the use of tiny and low profile inductors and ceramic capacitors.
