UCC24636DBVR Description

Short technical summary and product information.

The UCC24636DBVR from Texas Instruments is a secondary-side synchronous rectifier (SR) controller optimized for discontinuous/transition mode flyback converters. It supports output voltages from 5V to 24V and operates with a wide VDD range of 3.6V to 28V.

This controller features ultra-low standby current consumption of 110 µA and an auto-detect standby mode that disables SR switching for reduced no-load power. It offers volt-second balance control for high rectifier efficiency and is compatible with PSR and SSR flyback controllers. The device operates at frequencies up to 130 kHz and includes adaptive gate drive clamp and open/short pin fault protection.

The UCC24636DBVR is supplied in a 6-pin SOT-23 package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C. This controller is designed to enhance the efficiency of power supplies by precisely controlling the synchronous rectifier MOSFETs.
