ADP2126 Datasheet (Analog Devices)

ADP2126, DC-to-DC Converters

The ADP2126/ADP2127 are high frequency, step-down, dc-todc converters optimized for portable applications in which board area and battery life are critical constraints.

The fixed 6 MHz operating frequency enables the use of tiny ceramic inductors and capacitors and the regulators use spread spectrum
