Industry’s fastest 600V gate driver for discrete power MOSFETs and IGBTs

Texas Instruments (TI) has introduced what it believes to be the industry’s fastest half-bridge gate driver for discrete power MOSFETs and IGBTs that operate up to 600V. The UCC27714 high-side, low-side driver with 4A source and 4A 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. 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 125ns across -40C to 125C and tight channel-to-channel delay matching of 20ns across -40C to 125C. The device eliminates the need for bulky gate drive transformers, saving significant board space in high-frequency switch-mode power electronics. Key features : 1 - Smaller footprint creates highest power-density solutions: The UCC27714 reduces gate driver component footprint by 50 percent in secondary-side controlled power supplies. 2 - Advanced noise toleration: Negative voltage handling of -6V at the switched-node pin creates the ability to tolerate noise, causing virtually no malfunctions in the electronic system. 3 - MOSFETs have the ability to drive over a wide power range: The device’s high-current capability of 4A enables MOSFETs to drive over a wide power range, from a few Watts to a kW. 4 - Operates across wide temperatures: All electrical characterizations have little variations across operating temperatures, creating a simplified design and speeding time to market. Complementary devices to maximize system performance - Every gate driver in a system requires the appropriate controller for the end application. TI offers several pulse-width modulation (PWM), resonant, power factor correction (PFC) and digital power controllers. With the UCC27714 and TI’s recently released UCC29950 combination PFC (power factor correction) + LLC controller, designers can develop a complete, offline AC/DC power supply rated up to a few hundred Watts. The fully internalized PFC compensation of UCC29950 reduces design steps enabling fast time-to-market while the three-level over current protection and hiccup mode operation ensures a robust operation under short circuits and overload conditions, says the company. Tools and support to speed design - TI offers a broad range of support tools for the UCC27714 to speed time to market. The UCC27714 is now available in the TI store and through the company’s authorized distribution network. The high-speed 600V high-side low-side gate driver comes in a small outline integrated circuit (SOIC)-14 package.
