RT6575DGQW(2)

Overview

The RT6575DGQW(2) is a dual-channel synchronous DC/DC step-down controller with integrated 5V and 3.3V LDOs, designed for battery-powered systems. It features four outputs: two adjustable buck channels and two fixed LDOs. The device operates within an input voltage range of 5V to 25V and supports switching frequencies of 300kHz and 355kHz. It is housed in a 20-WQFN (3x3) package with exposed pad, suitable for surface mount installation.

Feature Summary

• Dual-channel synchronous buck topology for efficient power conversion
• Integrated fixed 5V and 3.3V low-dropout regulators
• Built-in sequencing control for output management

Applications

• Battery-powered portable electronic systems
• General purpose power supply generation
• Embedded system voltage regulation

Procurement Notes

Verify the exact suffix and manufacturer designation when ordering, as distributor listings may vary in packaging or revision codes. Confirm RoHS compliance and moisture sensitivity level requirements against your assembly process specifications before finalizing procurement.

Selection Notes

Select this component when a compact solution is required for generating multiple regulated voltages from a single battery source. The integrated LDOs simplify design by reducing external component count compared to discrete regulator solutions.

Part Context

This part belongs to the RT6575 family of PMICs from Richtek Technology Corporation. It is specifically engineered as a power management integrated circuit combining switching regulators and linear regulators to serve as a central power distribution unit in mobile applications.
