RT8130BGQW

Overview

The RT8130BGQW is a synchronous buck PWM controller manufactured by Richtek USA Inc. It operates with a fixed switching frequency of 300 kHz and supports an input voltage range of 4.5V to 13.2V. The device provides a single positive output configured for step-down conversion, featuring a maximum duty cycle of 88%. It is housed in a compact 10-WDFN (3x3) package with an exposed pad and functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Integrates synchronous rectification for improved power efficiency
• Includes enable pin control and Power Good status indication
• Supports phase control capabilities for multi-phase configurations

Applications

• Point-of-load DC-DC converter designs
• General purpose step-down power regulation
• Embedded system power management

Procurement Notes

Verify the specific suffix BGQW against the manufacturer datasheet to confirm package type and temperature grade. Ensure compatibility with the target PCB footprint for the 10-WDFN package. Confirm RoHS compliance requirements match project specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-output synchronous buck solution is required with a 300 kHz switching frequency. It is suitable for applications needing an input voltage up to 13.2V and operating temperatures up to 85°C. Consider the 10-WDFN package size for space-constrained layouts.
