Product Details

GENERAL DESCRIPTION

 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

 and transient response. To ensure the longest battery life in portable applications, the ADP2108

 has a power save mode that reduces the switching frequency under light load conditions.
