Overview
The RT8208AGQW is a high-performance, single synchronous buck controller from Richtek USA Inc. It features a resistor-programmable output voltage range from 0.75V to 3.3V. The device operates with a supply voltage of 4.5V to 5.5V and utilizes a 16-WQFN (3x3) package with an exposed pad. It supports surface mount mounting and functions within an operating temperature range of -40°C to 85°C.
Feature Summary
- Single positive output configuration for step-down DC-DC conversion
- Resistor programmable output voltage capability
- Integrated synchronous rectifier design
Applications
- Low-voltage point-of-load regulation
- Portable electronic devices requiring efficient power management
- Industrial control systems with single-phase buck requirements
Procurement Notes
Verify the specific datasheet version and ordering suffixes directly with Richtek USA Inc. or authorized distributors. Confirm RoHS compliance status and lead-free specifications prior to procurement. Ensure the 16-WQFN package dimensions match your PCB footprint requirements. Cross-reference part numbers to avoid confusion with similar family members.
Selection Notes
Select this component when a single-phase synchronous buck controller is required with a fixed input supply range of 4.5V to 5.5V. It is suitable for applications needing an output voltage between 0.75V and 3.3V set via external resistors. Consider the 16-WQFN package size for space-constrained designs requiring surface mount technology.
Part Context
This part belongs to the Richtek DC-DC switching controllers family, specifically designed as a buck regulator. It is distinct from linear regulators like the RT8205 series. The AGQW suffix indicates the specific package and temperature grade configuration within the product line.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pin compatibility and electrical parameters before replacing. No direct public substitute part numbers are confirmed in the provided data.
