NW23150

NW23150 is a high efficiency synchronous step-up converter that can provide up to 1.5A to a boosted output up to 5V 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 1MHz 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.

NW23150 is housed in a tiny SOT23-6 package.
