RT6575BGQW(2)

Overview

The RT6575BGQW(2) is a dual-channel synchronous DC/DC step-down controller integrated with two low-dropout regulators (LDOs). It features a wide input voltage range of 5V to 25V and operates at switching frequencies of 300kHz and 355kHz. The device provides four outputs: two adjustable buck channels and two fixed LDO outputs delivering 5V and 3.3V respectively. Packaged in a 20-WQFN (3x3) surface-mount footprint, it supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Integrates dual-channel synchronous buck controllers with dedicated 5V and 3.3V LDOs for comprehensive power management.
• Supports wide input voltage operation suitable for battery-powered systems requiring stable supply generation.

Applications

• Generating supply voltages for battery-powered systems
• Dual-channel step-down control applications

Procurement Notes

Verify the specific suffix designation against official Richtek documentation to confirm pin compatibility and functional equivalence. Ensure that ordering requirements align with manufacturer specifications regarding package type and moisture sensitivity levels before procurement.

Selection Notes

Select this component when a compact solution is required for generating multiple regulated rails from a single input source. The integration of both switching regulators and linear regulators reduces external component count and board space compared to discrete solutions.

Part Context

This part belongs to the RT6575 family of power management ICs designed for efficient energy conversion. It serves as a specialized controller within Richtek's portfolio for portable electronics and embedded systems requiring multi-rail power distribution.
