AN30185A-VL

Overview

The AN30185A-VL is a power management LSI integrating two synchronous step-down (buck) converters and one linear low-dropout (LDO) regulator. It employs a hysteretic control system for the DC-DC regulators, operating at a switching frequency of 1.2MHz. The device provides output voltages of 1.8V at 0.8A and 1V at 0.8A. Packaged in a 24HQFN format, it serves as a compact power solution for low-voltage applications requiring multiple regulated rails.

Feature Summary

• Integrates dual synchronous buck converters with hysteretic control
• Includes a dedicated linear low-dropout regulator
• Operates at a high switching frequency of 1.2MHz

Applications

• Low-voltage electronic systems
• Portable devices requiring multiple power rails
• Embedded power management solutions

Procurement Notes

Verify the specific suffix 'VL' against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure the package type matches the 24HQFN specification. Cross-reference ordering information directly with Panasonic Electronic Components documentation to avoid discrepancies in variant definitions.

Selection Notes

Select this component when a single IC solution is needed for generating both switched and linear regulated voltages. The integrated design reduces board space compared to discrete components. Verify that the required output currents of 0.8A per buck channel meet the system load requirements before finalizing the selection.

Part Context

This part belongs to the AN30185 series of power management LSIs from Panasonic Electronic Components. These devices are designed to consolidate power regulation functions into a single chip, simplifying circuit design for consumer electronics and industrial applications that require efficient power conversion and stable voltage outputs.

Replacement Considerations

Consult official substitution guides for compatible parts within the same family or equivalent multi-rail PMICs. Verify functional compatibility regarding control topology and output specifications before considering alternatives.
