ETA ETA1043
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. This eliminates the need for an external MOSFET and its control circuitry to disconnect the input from output, and provides robust output overload protection. ETA1043 is in a tiny DFN2x2-8L package.DESCRIPTION
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. A switching frequency of 1.2MHZ minimizes solution footprint by allowing the use of tiny and low profile inductors and ceramic capacitors. An internal synchronous MOSFET provides highest efficiency and with a current mode control that is internally compensated, external parts count is reduced to minimal.
