ADP2106 Datasheet Step-down DC-to-dc Converter

Manufacturer: Analog Devices

Overview: Data Sheet.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The ADP2105/ADP2106/ADP2107 are low quiescent current, synchronous, step-down dc-to-dc converters in a compact 4 mm × 4 mm LFCSP package.

At medium to high load currents, these devices use a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response.

To ensure the longest battery life in portable applications, the ADP2105/ADP2106/ADP2107 use a pulse frequency modulation (PFM) control scheme under light load conditions that reduces switching frequency to save power.
