Overview
The RT8816CGQW is a synchronous step-down switching controller manufactured by Richtek USA Inc. It features a Buck topology with four output channels and operates at a fixed switching frequency of 300 kHz. The device supports an input voltage range up to 32V and provides adjustable output voltages between 1.33 V and 2 V. It is housed in a WQFN-20 package, rated for operation from -10°C to +105°C, and complies with RoHS standards.
Feature Summary
- Synchronous Buck topology for high-efficiency power conversion
- Integrated control for four independent output channels
- Fixed 300 kHz switching frequency for optimized component size
- Wide operating temperature range suitable for demanding environments
Applications
- General-purpose DC-DC step-down power supply designs
- Embedded systems requiring multi-rail low-voltage power distribution
- Industrial equipment power management modules
- Consumer electronics internal power regulation
Procurement Notes
Verify the specific suffix 'CGQW' against the manufacturer's current datasheet to confirm pinout compatibility and thermal pad specifications. Ensure that the required output voltage range aligns with the 1.33 V to 2 V specification. Confirm that the 300 kHz switching frequency meets the electromagnetic interference requirements of the target application. Check for any recent product change notifications regarding the WQFN-20 package dimensions.
Selection Notes
Select this component when a compact, multi-output solution is required for low-voltage applications. The fixed 300 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the WQFN-20 package for space-constrained PCB layouts. Evaluate the -10°C to +105°C operating range against the environmental conditions of the final assembly to ensure reliable performance under thermal stress.
Part Context
The RT8816CGQW belongs to the RT8816 family of synchronous buck controllers from Richtek. This series is designed for applications requiring multiple regulated outputs from a single controller IC. The CGQW variant specifically denotes the WQFN-20 package configuration. It serves as a power management integrated circuit (PMIC) within the broader category of switching controllers, providing centralized control for complex power architectures.
Replacement Considerations
The RT8816CN-A is listed as an alias for this part number. Verify functional equivalence before substitution. No other cross-referenced substitutes are confirmed in the provided documentation.
