UCC24610DRBR

The Texas Instruments UCC24610DRBR is a secondary-side synchronous rectifier controller optimized for 5-V systems. It supports various topologies including Active-clamp flyback, Active-clamp forward, Buck-Boost, CCM, DCM, Flyback, Forward, Half bridge, LLC, LLC half-bridge, and Quasi resonant.

Key electrical specifications include an operating voltage range of 4.5V to 5.5V and an operating current of 2.15 mA. The device operates at up to 600 kHz and features VDS MOSFET-sensing with 1.6-Ω sink and 2.0-Ω source gate-drive impedances. It also offers a typical turnoff propagation delay of 20 ns.

This controller is designed for improved efficiency and design flexibility over traditional diode solutions. It includes features like Automatic Light Load Management and Synchronous Wake-Up From Sleep and Light-Load Modes. Protection features are available on programming inputs, and it has a SYNC input for CCM operation.

The UCC24610DRBR is available in an 8-SON (3x3) package and is surface-mountable. Its operating temperature range is -40°C to 125°C. Applications include AC-to-DC 5-V adapters, 5-V bias supplies, low voltage rectification circuits, and Flyback and LLC converters.
