S-8520D29MC-BVOT2U

Overview

The S-8520D29MC-BVOT2U is a step-down DC-DC switching controller manufactured by ABLIC Inc. It operates within an input voltage range of 2.5 V to 16 V and provides a fixed output voltage of 2.9 V. The device features a PWM control method with a switching frequency of 300 kHz and maintains a typical quiescent current of 100 uA. Packaged in a compact SOT-23-5 format, it is designed for efficient power management in space-constrained applications.

Feature Summary

• Integrates a synchronous buck converter controller optimized for low-power operation
• Utilizes Pulse Width Modulation (PWM) for stable voltage regulation under varying load conditions
• Designed for high efficiency through minimized internal power consumption

Applications

• Portable electronic devices requiring efficient step-down power conversion
• Battery-powered systems needing extended operational life
• Embedded circuits utilizing fixed 2.9 V logic levels

Procurement Notes

Verify the specific suffix BVOT2U against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.9 V output is required from a wide input voltage range up to 16 V. The 300 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 100 uA quiescent current for battery-operated designs where standby power consumption is critical.
