Power Integrations InnoMux-2 switcher ICs

Monday, 08 April, 2024 | Supplied by: Power Integrations


Power Integrations’ InnoMux-2 family of single-stage, independently regulated multi-output offline power-supply ICs consolidate AC-DC and downstream DC-DC conversion stages into a single chip, providing up to three independently regulated outputs for use in applications requiring multiple voltages.

The elimination of separate DC-DC stages reduces component count and PCB footprint while increasing efficiency in comparison to traditional two-stage architectures. Efficiency is aided by the ICs’ 750 V PowiGaN gallium-nitride transistors, zero-voltage switching (without an active clamp) and synchronous rectification.

InnoMux-2 ICs deliver up to 90 W of output power with regulation of better than ±3% across the full input line, load, temperature and differential current step conditions, according to Power Integrations. The InnoMux-2 controller also manages light-load power delivery, avoiding the need for pre-load resistors and reducing no-load consumption to less than 30 mW.

InnoMux-2 devices leverage Power Integrations’ thermally efficient InSOP24 and InSOP28 packages with PCB cooling, so no heatsink is required. Device options include dual- and three-output constant voltage (CV); optionally, one output may be dedicated to constant current (CC) drive, suitable for powering LEDs in displays or for high-speed charging of an internal battery.

Typical applications include TVs, monitors, appliances, networking, home and building automation, LED emergency lighting and industrial power supplies.
