ADP5020 - Analog Devices

ADP5020 Power Management

The ADP5020 provides a highly integrated power solution that includes all of the power circuits necessary for a digital imaging module. It comprises two step-down dc-to-dc converters, one LDO, and a power sequence controller. All dc-to-dc converters integrate power pMOSFETs and nMOSFETs, making the system simpler and more compact and reducing the cost. The A.
