Intersil’s 600-Volt Switching Mode Power Supply IGBT Family Targets High Voltage, High Current Offline Power Conversion

— IGBT offers alternative to conventional MOSFET technology
— First IGBT appropriate for high frequency power conversion

PALM BAY, FL, October 22, 1999 — Intersil Corporation today introduced the newest device in its family of switching mode power supply (SMPS) series IGBTs. The advanced SMPS 600-Volt (V) IGBT family is the first to offer high frequency offline power conversion for applications of

100 kilohertz (kHz) and greater. The device delivers high current density capability resulting in increased power supply power density for SMPS AC/DC, high voltage DC/DC, power factor

correction (PFC) stages and uninterruptible power supply (UPS) applications.

Intersil’s SMPS HGTG20N60A4 family of IGBT devices are MOS gated, high voltage switching devices combining the best features of MOSFETs and bipolar transistors. The devices deliver the high input impedance of a MOSFET and the low on state conduction loss of a bipolar transistor. The family is designed for high voltage switching applications where operating frequencies are high and where low conduction losses are essential.

Intersil’s SMPS family IGBT devices function as alternatives to power MOSFETs in high frequency, switchmode power converters. The devices deliver lower gate charge in comparison with MOSFETs, lowering peak current drive requirements. A single SMPS IGBT from Intersil can replace as many as four high voltage MOSFETs. Up to two die sizes smaller, the SMPS IGBT reduces board space and component count. When employing Intersil’s 600V SMPS IGBTs, designers can improve system efficiency while reducing costs.

"Intersil continues to demonstrate its commitment to the development of IGBT technology," said Peter Holdman product marketing manager at Intersil. "The HGTG20N60A4 family of SMPS series 600V IGBTs demonstrates the latest in IGBT technology enabling increased system power output, reliability and efficiency while reducing switching losses. Intersil’s continuous development of technology is resulting in viable, single device alternatives to designers who previously had to choose between power MOSFETs and bipolar transistors."

SMPS technology is the first IGBT technology appropriate for high frequency power conversion, operating at frequencies of 100kHz and greater. Intersil’s HGTG20N60A4 family features low on state voltage drop with a collector to emitter saturation voltage of 1.6V typical at 125 degrees Celsius. The current fall time of 70ns typical at 125 degrees Celsius results in reduced current full-time. A potential reduction in magnetic material cost results from an increase in switching frequency. Operating and storage junction temperature range is sustained through the potential reduction in reduced heatsink size and cost.
