AN30182A-PB

Overview

The AN30182A-PB is a power management integrated circuit manufactured by Panasonic Electronic Components. It integrates multiple voltage regulation functions within a single package, specifically combining switching and linear regulator technologies. The device features eight output channels, comprising two synchronous DC-DC step-down regulators and six low-dropout (LDO) regulators. This configuration allows for efficient power conversion and stable voltage supply in compact electronic designs.

Feature Summary

• Integrates dual synchronous buck converters and six LDO regulators
• Supports wide input voltage range from 1.7V to 5.5V
• Designed for high-efficiency power management in portable devices

Applications

• Portable consumer electronics requiring multi-rail power supplies
• Mobile communication devices needing efficient voltage regulation
• Embedded systems with space-constrained power architectures

Procurement Notes

Verify the manufacturer designation carefully, as sources list both Panasonic and Switchcraft Inc. Confirm the exact suffix and package type against official datasheets. Ensure compliance with RoHS requirements if specified for your application. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when an application requires multiple regulated voltages from a single IC to save board space. Consider the thermal performance of the 24WLCSP or 25WLCSP package for your enclosure design. Evaluate the current capabilities of the buck and LDO sections against your load requirements before finalizing the design.

Part Context

This part belongs to the AN3018x series of power management ICs. It is designed to replace discrete regulator solutions, offering a consolidated approach to power distribution. The integration of both switching and linear regulators provides flexibility for different noise-sensitive and efficiency-critical rails within the same system.

Replacement Considerations

Check for pin-compatible alternatives from Panasonic or other manufacturers. Verify that substitute parts offer equivalent output currents and voltage ranges. Ensure the replacement supports the required operating temperature range of -30°C to 85°C.
