Intersil Holding Introduces New Switch-Mode Power Supply 600V IGBTs

March 26, 2000 by Jeff Shepard

Intersil Holding Corp. (Palm Bay, FL) introduced the devices in its family of switch-mode power supply (SMPS) series IGBTs to address the 24 x 7 power-management demands of today's Internet infrastructure.

The advanced SMPS 600V family of IGBTs is tailored for the high-current power densities and high-frequency switching requirements of power supplies and telecom switches that comprise the backbone of today's Internet. Intersil's SMPS IGBT devices are MOS-gated, high-voltage switching devices combining what Intersil claims are the best features of MOSFETs and bipolar transistors. The devices are designed to deliver the high-input impedance of a MOSFET and the low on-state conduction of a bipolar transistor.

The SMPS family is suitable for high-voltage switching applications where high operating frequencies and low switching/conduction losses are essential, including ac/dc SMPS, high-voltage dc/dc, PFC stages and UPSs. The IGBT devices function as alternatives to power MOSFETs in high-frequency, switch-mode power converters. The devices deliver lower gate charge in comparison with MOSFETs, lowering peak-current drive requirements.

According to Intersil, a single SMPS IGBT from Intersil can replace as many as three high-voltage MOSFETs. Up to one-fifth the size of a comparable MOSFET solution, an SMPS IGBT solution reduces board space and component count. When employing Intersil's 600V SMPS IGBTs, designers can improve system reliability and efficiency while reducing costs.
