ADP5033ACBZ-3-R7

Overview

The ADP5033ACBZ-3-R7 is a power management IC featuring two synchronous buck converters and two low-dropout regulators. It operates with an input voltage range of 2.3 V to 5.5 V. The buck regulators provide up to 800 mA output current, while the LDOs deliver 300 mA each. Fixed output voltages are 1.2 V, 1.8 V, and 3 V for the buck channels, with 3 V fixed outputs for the LDOs. The device supports a switching frequency of 3 MHz and functions within a temperature range of -40°C to +125°C.

Feature Summary
