RT8130CGQW

Overview

The RT8130CGQW 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 2.5 V to 21 V. The device provides a single positive output configured for voltages between 5 V and 12 V, with a maximum duty cycle of 88%. It utilizes a 10-WDFN (3x3) package with an exposed pad for surface mount installation. The component functions within a temperature range of -40°C to +85°C and includes control features such as enable, phase control, and power good signaling.

Feature Summary

• Synchronous rectification architecture for high efficiency
• Integrated power good signal and enable functionality
• Phase control capability for multi-phase expansion

Applications

• Point-of-load regulation in computing systems
• General purpose DC-DC conversion modules
• Industrial equipment power distribution

Procurement Notes

Verify the specific suffix 'CGQW' against the manufacturer's current datasheet to confirm pinout compatibility and thermal specifications. Ensure that the 10-WDFN package dimensions align with the target PCB footprint. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning.

Selection Notes

Select this component when a fixed 300 kHz frequency is required for EMI management. The wide input voltage range up to 21 V allows flexibility in system design. Consider the 10-WDFN package size constraints and thermal dissipation needs relative to the expected load conditions.
