Compact isolated driver family for 1700 V IGBTs
Power Integrations has added new drivers to its family of galvanically isolated single-channel gate driver ICs.

The new Scale-iDriver devices support IGBT blocking voltages up to 1700 V, which are generally used in 400 VAC and 690 VAC line applications. They also support the latest three-level topology photovoltaic inverters and for photovoltaic arrays leveraging the new 1500 V DC bus standard.

The 1700 V devices are optimized for driving both IGBTs and MOSFETs by combining Power Integrations’ pioneering FluxLink magneto-inductive bi-directional communications technology and SCALE power device driver technology. FluxLink eliminates the need for unreliable opto-electronics and the associated compensation circuitry, thereby enhancing operational stability while reducing system complexity, and SCALE technology incorporates all key gate driver functions into an ASIC, reducing size and improving reliability while simplifying design. Innovative eSOP package features greater than 9.5 mm of creepage and a CTI of 600, ensuring substantial operating voltage margin and high system reliability.
