Overview
The RT8152BGQW is a single-output step-down DC-DC controller manufactured by Richtek USA Inc. It operates with an input voltage range of 4.5V to 25V and provides a regulated output voltage. The device utilizes VID (Voltage ID) technology for precise voltage setting, making it suitable for high-efficiency power conversion applications requiring flexible output configuration.
Feature Summary
- Integrates VID interface for direct microprocessor communication
- Supports synchronous buck topology for high efficiency
- Designed for wide input voltage ranges up to 25V
Applications
- AMD SVI2 mobile CPU power supplies
- Server and workstation mainboard VRMs
- High-performance computing graphics power stages
Procurement Notes
Verify the specific suffix 'GQW' against the manufacturer's latest datasheet to confirm pinout compatibility and thermal pad specifications. Ensure that the ordering documentation explicitly references the Richtek USA Inc. part number to avoid confusion with similar legacy or alternative package variants within the same product family.
Selection Notes
Select this component when a dedicated PWM controller with VID control is required rather than an integrated regulator. It is appropriate for designs where the external MOSFET selection must be customized for current handling capabilities. Consider the WQFN-32 package constraints for PCB layout and thermal dissipation requirements during the initial schematic phase.
Part Context
This component belongs to the Richtek PMIC series focused on multi-phase power management for advanced processors. It serves as a control unit rather than a complete converter, relying on external power stages. The device addresses the need for dynamic voltage scaling in modern computing architectures.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing board layouts before considering any alternative controllers from different manufacturers.
