PRODUCT DESCRIPTION
The MD3156 is a step-up converter that provides a boosted output voltage from a low voltage source. Because of its proprietary design, it starts up at a very low input voltage down to 1.1V, and only consumes 15u A at standby, making it an ideal choice for single cell alkaline/Ni MH battery operations.
A switching frequency of 1MHz minimizes...
