RT6575EGQW(2)

Overview

The RT6575EGQW(2) is a power management integrated circuit featuring four outputs: two synchronous step-down (buck) converters and two low-dropout (LDO) regulators. It operates with an input voltage range of 2V to 25V. The switching frequencies are fixed at 300kHz for the first channel and 355kHz for the second. The device is housed in a 20-WQFN package measuring 3x3 mm.

Feature Summary

• Integrates dual synchronous buck controllers and dual LDOs for compact system design
• Includes internal sequencing logic for controlled power-up and power-down
• Supports wide input voltage range suitable for battery-powered applications

Applications

• Battery-powered portable electronic systems
• Embedded systems requiring multiple regulated supply rails
• Compact consumer electronics with space constraints

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the 20-WQFN 3x3mm package dimensions. Confirm RoHS compliance status if required by assembly specifications.

Selection Notes

Select this component when a single IC solution is needed to provide both high-efficiency switching regulation and low-noise linear regulation. The integrated sequencing feature simplifies board layout compared to using discrete controllers. Verify that the required output currents for the LDOs do not exceed the specified limits.

Part Context

This part belongs to the RT6575 family of multi-output PMICs from Richtek. Variants within the family, such as the RT6575DGQW(2), share similar architectural features but may differ in specific output configurations or packaging options. The EGQW variant specifically denotes the 20-WQFN package configuration.

Replacement Considerations

The RT6575BGQW is listed as a substitute option by distributors. Verify functional equivalence and pin compatibility before replacement.
