InnoMux-2: Power Integrations’ Latest GaN-based Switcher IC Family with Multiple Independently Regulated Outputs

InnoMux-2 ICs consolidate AC-DC and downstream DC-DC conversion stages into a single chip, providing up to three independently regulated outputs for use in white goods, industrial systems, displays, and other applications requiring multiple voltages. Eliminating separate DC-DC stages slashes component count, reduces PCB footprint, and increases efficiency by as much as ten percentage points compared 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.

Noted Roland Saint-Pierre, vice president of product development at Power Integrations, “Most modern electronic systems rely on multiple internal voltages to operate various functions such as computing, communication, and actuation function – typically heat, light, sound or motion of some kind. But losses in each conversion stage are compounded, degrading system performance and generating heat. The InnoMux-2 IC overcomes this challenge by providing up to three independently regulated voltage outputs or two voltage outputs and a constant current output from a single stage, achieving a compact and efficient power sub-system with low component count.”

InnoMux-2 ICs deliver up to 90 watts of output power with accurate regulation of better than ±3 percent across the full input line, load, temperature, and differential current step conditions. Total power system efficiency (AC to regulated low-voltage DC segment) is above 90 percent; the advanced 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. This conserves power for necessary application functionality subject to the 300 mW allowance for standby usage under the European energy-using product (EuP) regulations.

InnoMux-2 devices leverage Power Integrations’ thermally efficient InSOP™24 and InSOP™28 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.

Pricing for InnoMux-2 IMX2174F devices starts at $1.11 for 50,000-unit quantities. Datasheets, three reference design reports, and an introductory video are immediately available for download or viewing.
