Battery Charger Plus DC/DC

Combining a high performance battery charger with one or more integrated dc-to-dc regulators, Analog Devices’ multifunction products address battery charging and provide multiple system rails in portable products. A high level of integration is offered in a small footprint, with small total solution size and ease of use. The on-chip dc-to-dc regulator may be either a switching regulator for maximum efficiency and battery life or a linear regulator for simplicity.
