RT8238BGQW

Overview

The RT8238BGQW is a single synchronous buck PWM controller manufactured by Richtek. It operates with a fixed switching frequency of 200 kHz and supports an output voltage range from 500 mV to 3.3 V. The device provides an output current capability of 1 mA and functions within a temperature range of -40°C to +85°C. It utilizes a WQFN-12 package for surface mount installation.

Feature Summary

Single channel synchronous buck topology
Fixed 200 kHz switching frequency operation
Adjustable output voltage down to 500 mV

Applications

General purpose DC-DC conversion
Embedded system power supplies
Low power application circuits

Procurement Notes

Verify the specific suffix BGQW against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure compatibility with WQFN-12 footprint requirements during PCB layout. Check moisture sensitivity levels and recommended reflow profiles prior to assembly processing.

Selection Notes

Select this component when a single-channel synchronous buck control solution is required with a fixed 200 kHz frequency. It is suitable for applications needing low output voltages starting at 500 mV. Consider the 1 mA output current limit and WQFN-12 package constraints for thermal and space requirements.

Part Context

This part belongs to the Richtek RT8238 series of switching controllers. It is categorized under PMIC power management ICs. The device serves as a controller for external MOSFETs in buck converter topologies, distinct from integrated power stage solutions.
