Fastest 600-V Gate Driver Enables Higher Power Density

Fastest 600-V Gate Driver Enables Higher Power Density

Texas Instruments introduced the industry’s fastest half-bridge gate driver for discrete power MOSFETs and IGBTs that operate up to 600 V. The UCC27714 high-side, low-side driver with 4-A source and 4-A sink current capability reduces component footprint by 50 percent, enabling higher power density in high-frequency, offline AC/DC power supplies used in server, telecom and industrial designs including uninterruptible power supplies. For more details, see http://www.ti.com/UCC27714-pr-eu.

The UCC27714 delivers 90 nanosecond (ns) propagation delay, 40 percent lower than existing silicon solutions, tight control of the propagation delay with a maximum of 125 ns across -40 C to 125 C and tight channel-to-channel delay matching of 20 ns across -40 C to 125 C.  The device eliminates the need for bulky gate drive transformers, saving significant board space in high-frequency switch-mode power electronics.
