ICE Components Offers High Creepage/Low Leakage Inductance Gate Drive Transformer

ICE Components, Inc. announced a product line expansion with the GT05 Series of Gate Drive transformers for use in off-line switching power supplies. The GT05 is based upon the GT03 series, but uses what is described as a new innovative header design to increase creepage and simplify assembly. ICE uses a toroid design in the design of both the GT03 Series and the GT05 Series.

Key features of each include low leakage inductance, multiple winding configurations, excellent E-T ratings, Hi-Pot ratings up to 3,750Vac and high creepage distances suitable for most applications. "The toroidal design of both the GT03 and GT05 Series provides a key benefit of low leakage inductance." said Robin Benas, Engineering Manager for ICE Components. "Much lower than what can be found in E core based designs. Low leakage inductance reduces time delay and ringing in the drive signal, which are key in gate drive circuit performance."quo;

The GT05 features E-T ratings up to 100V-uS and a creepage distance of 8.7mm. At just 11 x 13 x 6.8mm in size, the GT05"s SMT package is suitable for a wide variety of applications including high density dc-dc, high power ac-dc, medical and industrial.

The GT03 features three creepage distance options each with multiple E-T products and turns ratios. The -A is rated for a 1,500 Vac Hi-Pot and is suitable for working voltage applications. It features E-T products up to 110 V-uSec and six winding configurations. The -B has a creepage distance of 3mm and is Hi-Pot rated at 3,750Vac. It features an E-T rating up to 69 V-uSec and is available in three winding configurations. The -C has a creepage distance of 8mm and is Hi-Pot rated at 3,750 V-uSec. It features an E-T rating up to 69 V-uSec and is available in three winding configurations.

Parts are available with prices as low as $0.56 for 10k pcs of the GT05 and $0.58 for 10k pieces of the GT03-A. Individual parts pricing may vary due to volume and model.
