ADP5033ACBZ-7-R7

Overview

The ADP5033ACBZ-7-R7 is a power management integrated circuit from Analog Devices, classified as a switching voltage regulator. It integrates two synchronous buck converters and two low-dropout (LDO) regulators within a single package. The device provides four output channels: two buck regulators capable of delivering up to 800 mA each, and two LDOs providing 300 mA each. It operates with an input voltage range of 2.3 V to 5.5 V and supports a switching frequency of 3 MHz. The component features a shutdown function and maintains a typical quiescent current of 380 uA. It is designed for operation across a temperature range of -40°C to +125°C and is supplied in a WLCSP-16 package.

Feature Summary

• Integrates dual high-current buck regulators and dual LDOs for comprehensive power distribution
• Supports high-frequency switching at 3 MHz to minimize external passive component size
• Includes a dedicated shutdown pin for system power management and energy conservation

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-powered systems needing efficient step-down conversion
• Embedded applications utilizing the ADP5033 family architecture

Procurement Notes

Verify the specific suffix code against official Analog Devices documentation to confirm fixed output voltages, as variants within the ADP5033 series differ in internal resistor networks. Confirm package type and thermal specifications match the target PCB layout requirements. Ensure compatibility with the intended input voltage range and load conditions before integration.

Selection Notes

Select this component when a compact solution is required for generating multiple voltage levels from a single source. The integrated nature reduces board space compared to discrete solutions. Consider the 3 MHz switching frequency for applications prioritizing small inductor sizes. Verify that the total current demands of the buck and LDO outputs align with the device's specified limits.

Part Context

This part belongs to the ADP5033 series of power management ICs. The series is characterized by its ability to combine switching regulators with linear regulators in a single footprint. Other variants in the series, such as ADP5033ACBZ-3-R7, may offer different fixed output configurations or slight parameter variations while maintaining the same core topology and package style.

Replacement Considerations

Direct substitutes include other ADP5033ACBZ variants with matching suffixes if output voltage requirements differ. Cross-referencing with similar multi-output PMICs from Analog Devices requires verification of pin compatibility and electrical specifications.
