RT6585BGQW(2)

Overview

The RT6575BGQW is a dual-channel synchronous buck converter controller with integrated LDOs, designed for portable devices. It features two adjustable synchronous buck outputs and two fixed LDO outputs (3.3V/100mA and 2V-5.5V). Operating from a 5V to 25V supply, it supports switching frequencies of 300kHz and 355kHz. The device includes sequencing control and is housed in a compact 20-WQFN (3x3) package. It operates within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Integrates two synchronous buck converters and two low-dropout regulators in a single package
• Provides hardware sequencing control for multi-rail power-up sequences
• Supports wide input voltage range suitable for battery-powered applications

Applications

• Portable electronic devices requiring multiple voltage rails
• Smartphones and tablets
• Digital cameras
• Network communication devices

Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to ensure pin compatibility and electrical specifications match your design requirements. Confirm RoHS compliance status and moisture sensitivity level before integration into the production line.

Selection Notes

Select this component when a compact solution combining both switching regulation and linear regulation is required. It is suitable for systems needing synchronized buck outputs alongside fixed or adjustable LDO rails within a small footprint constraint.
