ADI ADP2108AUJZ-1.8-R7

降压降压2.3V5.5V600mA

Overview

The ADP2108AUJZ-1.82R7 is a high efficiency, low quiescent current step-down 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 ADP2108AUJZ-1.82R7 has a power save mode that reduces the switching frequency under light load conditions.

Other key features include undervoltage lockout to prevent deep battery discharge and soft start to prevent input current over-shoot at startup. The ADP2108AUJZ-1.82R7 is available in 5-ball WLCSP and 5-lead TSOT packages. The ADP2109 provides the same features and operations as the ADP2108AUJZ-1.82R7 and has the additional function of a discharge switch in the WLCSP package.
