ADP2108ACBZ-1.8-R7

ADP2108 is a high efficiency, low quiescent current stepdown dc-to-dc converter. 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 device has a power save mode that reduces the switching frequency under light load conditions. The device has an internal soft start and is internally compensated. During logic controlled shutdown, the input is disconnected from the output and the device draws less than 1μA from the input source. It features include under voltage lockout to prevent deep battery discharge and soft start to prevent input current overshoot at start-up. It is widely used in application such as PDAs and palmtop computers, wireless handsets, digital audio, portable media players, digital cameras, GPS navigation units etc.
