New GaN-based ICs combine AC-DC and DC-DC
stages into a single power converter; cut power system losses by up
to 50 percent
APEC 2024 – Power Integrations (NASDAQ: POWI), the leader
in high-voltage integrated circuits for energy-efficient power
conversion, today announced the InnoMux™-2 family of single-stage,
independently regulated multi-output offline power-supply ICs.
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.
Elimination of separate DC-DC stages slashes component count,
reduces PCB footprint and increases efficiency by as much as 10
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.

Roland Saint-Pierre, vice president of product development at
Power Integrations said: “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 output
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 functionality in
applications 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.
