Overview
The S-8520C31MC-BRQT2U is a step-down switching controller manufactured by ABLIC Inc. It operates within an input voltage range of 2.5V to 10V and provides a fixed output voltage of 3.1V. The device features a PWM control method with a switching frequency of 300kHz. It incorporates a low standby current of 100uA to enhance efficiency in battery-powered applications. The component is housed in a compact SOT-23-5 package, suitable for surface-mount assembly.
Feature Summary
- Step-down topology for efficient voltage reduction
- Low quiescent current for power conservation
- Fixed output voltage configuration
- Compact surface-mount packaging
Applications
- Battery-powered portable electronics
- Consumer devices requiring regulated power supplies
- Industrial control systems with limited space
- Automotive infotainment modules
Procurement Notes
Verify the exact suffix BRQT2U against official ABLIC documentation to confirm tape-and-reel packaging and specific binning. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement plans.
Selection Notes
Select this component when a fixed 3.1V output is required from a 2.5V to 10V input source. Consider the 300kHz switching frequency for inductor size trade-offs. Evaluate the 100uA standby current against system sleep mode requirements. Confirm thermal performance within the SOT-23-5 package constraints for the intended load conditions.
Part Context
This part belongs to the S-8520 series of DC-DC switching controllers from ABLIC. The series focuses on low-power applications with integrated MOSFETs or external driver capabilities. The S-8520C31MC variant specifically targets fixed-output applications, distinguishing itself from adjustable versions through its internal resistor network setting the output voltage.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications with potential alternatives from other manufacturers before substitution.
