Energy Integrations, a frontrunner in high-voltage built-in circuits for energy-efficient energy conversion, has launched the world’s highest-voltage, single-switch gallium-nitride (GaN) energy provide built-in circuit (IC). This new launch includes a exceptional 1250-volt PowiGaN swap. These InnoSwitch3-EP 1250 V ICs symbolize the most recent additions to Energy Integrations’ InnoSwitch household, designed for off-line fixed voltage/fixed present (CV/CC) QR flyback switcher ICs.
The InnoSwitch line boasts synchronous rectification, FluxLink safety-isolated suggestions, and a variety of swap choices, together with 725 V silicon, 1700 V silicon carbide, and now PowiGaN variants in 750 V, 900 V, and 1250 V.
One of many standout options of Energy Integrations’ proprietary 1250 V PowiGaN expertise is its remarkably low switching losses, measuring lower than one-third of these present in equal silicon units on the similar voltage. This attribute ends in a staggering energy conversion effectivity of as much as 93%, enabling the creation of extremely compact flyback energy provides able to delivering as much as 85 W with out the necessity for a heatsink.
Radu Barsan, the Vice President of Know-how at Energy Integrations, highlighted the corporate’s dedication to pushing the boundaries of high-voltage GaN expertise. He famous, “Energy Integrations continues to advance the cutting-edge in high-voltage GaN expertise growth and industrial deployment, rendering even the perfect high-voltage silicon MOSFETs out of date alongside the best way. We have been first to market with high-volume shipments of GaN-based power-supply ICs in 2019, and earlier this yr launched a 900-volt model of our GaN-based InnoSwitch merchandise. Our ongoing growth of upper voltage GaN expertise, illustrated right here by our new 1250 V units, extends the effectivity advantages of GaN to a fair wider vary of functions, together with many presently served by silicon-carbide expertise.”
Designers incorporating the InnoSwitch3-EP 1250 V ICs into their tasks can confidently specify an working peak voltage of 1000 V, permitting for an industry-standard 80% de-rating from the 1250 V absolute most. This substantial headroom is especially useful in difficult energy grid environments the place robustness is important to defend in opposition to grid instability, surges, and different energy perturbations.
