General Description

The ADP5023 combines two high performance buck regulators and one low dropout (LDO) regulator in a small, 24-lead 4 mm × 4 mm LFCSP to meet demanding performance and board space requirements.

The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space.

When the MODE pin is set high, the buck regulators operate in forced PWM mode.

Overview

Data Sheet Dual 3 MHz, 800 mA Buck Regulators with One 300 mA.
