ADP2121 Datasheet (Analog Devices) - Synchronous Step-Down DC-to-DC Converter

ADP2121, Synchronous Step-Down DC-to-DC Converter

The ADP2121 is a high frequency, low quiescent current step-down dc-to-dc converter optimized for portable applications in which board area and battery life are critical constraints.

The 6 MHz operating frequency enables the use of tiny ceramic inductors and capacitors.

Additionally, the synchronous
