InnoSwitch3-EP 1250 V ICs underline company’s
continued leadership in high voltage GaN technology
ECCE 2023 – Power Integrations (NASDAQ: POWI), the leader
in high-voltage integrated circuits for energy-efficient power
conversion, today released the world’s highest-voltage,
single-switch gallium-nitride (GaN) power supply IC, featuring a
1250-volt PowiGaN™ switch. InnoSwitch™3-EP 1250 V ICs are the
newest members of Power Integrations’ InnoSwitch family of off-line
CV/CC QR flyback switcher ICs, which feature synchronous
rectification, FluxLink™ safety-isolated feedback and an array of
switch options: 725 V silicon, 1700 V silicon carbide, and PowiGaN
in 750 V, 900 V and now 1250 V varieties.

The switching losses for Power Integrations’ proprietary 1250 V
PowiGaN technology are less than a third of that seen in equivalent
silicon devices at the same voltage. This results in power
conversion efficiency as high as 93 percent – enabling highly
compact flyback power supplies that can deliver up to 85 W without
a heatsink.
Radu Barsan, vice president of technology at Power Integrations,
said: "Power Integrations continues to advance the state of the art
in high-voltage GaN technology development and commercial
deployment, rendering even the best high-voltage silicon MOSFETs
obsolete along the way. We were first to market with high-volume
shipments of GaN-based power-supply ICs in 2019, and earlier this
year introduced a 900-volt version of our GaN-based InnoSwitch
products. Our ongoing development of higher voltage GaN technology,
illustrated here by our new 1250 V devices, extends the efficiency
benefits of GaN to an even wider range of applications, including
many currently served by silicon-carbide technology.”
Designers using the new InnoSwitch3-EP 1250 V ICs can
confidently specify an operating peak voltage of 1000 V, which
allows for industry-standard 80 percent de-rating from the 1250 V
absolute maximum. This provides significant headroom for industrial
applications and is particularly valuable in challenging power grid
environments where robustness is an essential defense against grid
instability, surge and other power perturbations.
