ADP2108 Step-Down DC-to-DC Converter

The ADP2108 is a high efficiency, low quiescent current stepdown dc-to-dc converter manufactured in two different packages. The total solution requires only three tiny external components. It uses a proprietary, high speed current mode, constant frequency PWM control scheme for excellent stability a.
