RT9385BGQW

Overview

The RT9385BGQW is a DC-DC regulator manufactured by Richtek USA Inc., utilizing a switched capacitor (charge pump) topology. It features five internal switches and provides five distinct outputs. The device operates with a minimum supply voltage of 2.8V.

Feature Summary

• Integrates multiple internal switches for efficient power conversion
• Provides five regulated output channels from a single charge pump architecture

Applications

• Multi-rail power distribution in portable electronics
• Biasing circuits requiring multiple voltage levels
• Power management for low-voltage digital logic systems

Procurement Notes

Verify the specific suffix 'BGQW' to confirm package type and temperature grade, as variations exist within the RT9385 family. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage requirements align with the specified 2.8V minimum operational threshold for reliable performance.

Selection Notes

Select this component when a compact solution for generating multiple voltages from a single low-voltage source is required. The charge pump topology eliminates the need for external inductors, saving board space. Verify that the total load current across all five outputs remains within the device's thermal and electrical limits for the intended application environment.

Part Context

This part belongs to the RT9385 series of LED drivers and regulators. While often categorized under LED lighting drivers due to common charge pump applications, this specific variant functions as a general-purpose multi-output DC-DC regulator. It shares architectural similarities with other Richtek charge pump devices but is distinguished by its five-output configuration.

Replacement Considerations

Check for direct pin-compatible alternatives within the RT9385 series or similar multi-output charge pumps from Richtek. Ensure any substitute maintains the five-output capability and compatible input voltage range.
