RT8125EGQW

Overview

The RT8125EGQW is a positive output step-down DC-DC controller IC manufactured by Richtek USA Inc. It operates with a fixed switching frequency of 300 kHz and supports an output voltage range from 300 mV to 3.3 V. The device provides an output current capability of 4 mA. It is designed for operation in environments with temperatures as low as -40 C. The component is housed in a 10-WDFN (3x3) package.

Feature Summary

Provides high efficiency and excellent transient response suitable for CPU core and I/O applications.

Applications

CPU core power supply
I/O power supply

Procurement Notes

Verify the specific suffix 'EGQW' against the official datasheet DS8125E-00.pdf to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement orders.

Selection Notes

Select this controller for applications requiring a fixed 300 kHz switching frequency and a maximum output current of 4 mA. Ensure the design accommodates the 10-WDFN (3x3) package constraints and operates within the specified minimum temperature of -40 C.

Part Context

This component belongs to the RT8125 family of PWM controllers, which are designed for high efficiency and high DC output accuracy. The EGQW variant specifically denotes the 10-WDFN package configuration used in compact power management solutions.

Replacement Considerations

The RT8125HGQW is a related model in the same family offering similar performance characteristics. Verify pin compatibility and specific electrical parameter differences before substituting.
