With a breakdown voltage of 1700 V, Power Integrations’ IMX2353F GaN switcher easily supports a nominal input voltage of 1000 VDC in a flyback configuration. It also achieves over 90% efficiency, while supplying up to 70 W from three independently regulated outputs.
The IMX2353F, part of the InnoMux-2 family of power supply ICs, is fabricated using the company’s PowiGaN technology. Its high voltage rating makes it possible for GaN devices to replace costly SiC transistors in applications like automotive chargers, solar inverters, three-phase meters, and other industrial power systems.
Like other InnoMux-2 devices, the IMX2353F provides both primary and secondary-side controllers, zero voltage switching without an active clamp, and FluxLink, a safety-rated feedback mechanism. Each of the switcher IC’s three regulated outputs is accurate to within 1%. By independently regulating and protecting each output, the IMX2353F eliminates multiple downstream conversion stages. The device has a switching frequency of 100 kHz and operates over a temperature range of -40°C to +150°C.
Prices for the IMX2353F start at $4.90 each in lots of 10,000 units. Samples and evaluation boards are available from Power Integrations and its authorized distributors.
