Description

The UCC2732x and UCC3732x family of high-speed dual-MOSFET Drivers deliver 4-A source and 4-A sink peak current to effectively drive MOSFETs where it is needed most at the Miller Plateau Region. A unique BiPolar and MOSFET hybrid output stage in parallel also allows efficient current sourcing and sinking at low supply voltages. Three standard logic options are offered — dual-inverting, dual-noninverting, and one-inverting and one-noninverting driver. Input thresholds are based on TTL and CMOS and independent of supply voltage and feature wide input hysteresis offering excellent noise immunity. The UCC2732x and UCC3732x family is available in the standard SOIC-8 (D) or PDIP-8 (P) packages as well as the thermally enhanced -8pin PowerPAD MSOP package (DGN), drastically lowering thermal resistance to improve long term reliability.

Description

The UCC3895EVM-001 is an isolated 48V input phase shifted full bridge converter providing an output of 3.3V at 15A. Using the AB outputs of the UCC3895, a novel technique for direct control driven synchronous rectification is demonstrated.

Features

Uses the A and B outputs of the UCC3895 along with a UCC37324 dual 4A MOSFET driver to implement direct control of a synchronous rectifier current doubler in a phase shifted full bridge topology. This technique provides the proper gating and timing signals necessary to accurately synchronize output (...)
