UCC24636DBVR

Power Supply Controllers, Monitors Overview

The UCC24636DBVR is a secondary-side controller for synchronous rectification in isolated power supplies, housed in a SOT-23-6 package. It operates on a supply voltage range of 3.6V to 28V and supports an operating temperature from -40°C to 125°C. The device features integrated high-current drivers with a peak output current capability of 5A. It includes built-in protection mechanisms such as overcurrent protection (OCP) and thermal shutdown to ensure reliable operation under fault conditions.

Power Supply Controllers, Monitors Feature Summary

• Integrated secondary-side control logic for synchronous rectifier management
• High-current gate driver outputs capable of driving multiple MOSFETs
• Built-in overcurrent protection and thermal shutdown safeguards

Power Supply Controllers, Monitors Applications

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'DBVR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the SOT-23-6 footprint matches the target PCB design guidelines. Ensure compliance with RoHS3 specifications and check moisture sensitivity level classifications prior to storage and handling procedures.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing isolated topologies requiring dedicated secondary-side control rather than primary-side regulation. Evaluate the 5A drive strength against the total gate charge requirements of the selected synchronous rectifier MOSFETs. Consider the wide input voltage range suitability for universal AC input applications.

Power Supply Controllers, Monitors Part Context

This part belongs to the UCC246xx family of synchronous rectifier controllers designed by Texas Instruments. These devices are engineered to replace traditional diode-based rectification, significantly improving conversion efficiency in low-voltage, high-current output stages of switching power supplies.
