Power Integrations 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.

Nexperia is once again bringing its product innovations to APEC and today announced the release of several new MOSFETs to further broaden its range of discrete switching solutions for use in various applications across multiple end markets.
This release includes 100 V application specific MOSFETs (ASFETs) for PoE, eFuse and relay replacement in 60% smaller DFN2020 packaging, and 40 V NextPowerS3 MOSFETs with improved electromagnetic compatibility (EMC) performance.
PoE switches typically have up to 48 ports, each requiring 2 MOSFETs for protection. With up to 96 MOSFETs on a single PCB, any reduction in device footprint is attractive. For this reason, Nexperia has released 100 V PoE ASFETs in 2 mm x 2 mm DFN2020 packaging which occupies 60% less space than previous versions in LFPAK33 packaging.
A critical function of these devices is to protect PoE ports by limiting inrush currents while safely managing fault conditions. To manage this scenario, Nexperia has enhanced the safe operating area (SOA) of these devices by up to 3x with only a minimal increase in RDS(on). These ASFETs are also suitable for battery management, Wi-Fi hotspot, 5G picocell and CCTV applications and can serve as replacements for mechanical relays in smart thermostats, for example.
EMC-related issues caused by MOSFET switching usually only emerge late in the product development life cycle and resolving them can incur additional R&D costs and delay market release. Typical solutions include using significantly more expensive MOSFETs with lower RDS(on) (to slow down switching and absorb excessive voltage ringing) or to fit an external capacitive snubber circuit but this approach has the disadvantage of increasing component count.
Nexperia has optimized its 40 V NextPowerS3 MOSFETs to offer similar EMC performance as that which can be achieved using an external snubber circuit, while also offering higher efficiency. These MOSFETs are suitable for use in switching converters and motor controllers across various applications and are available in LFPAK56 packaging.
“By introducing these latest additions to our range of discrete FET solutions at APEC 2024, Nexperia showcases how we leverage our expertise in R&D to deliver optimized solutions. Both our new 100 V PoE ASFETs as well as improved EMC performance in our 40 V NextPowerS3 MOSFETs demonstrate our commitment to supporting engineers in overcoming challenges across diverse applications. These innovations underscore Nexperia’s dedication to providing efficient, compact, and reliable solutions that empower our customers to succeed in today’s ever-evolving market,” says Chris Boyce, MOSFET Marketing & Product Group Director at Nexperia.

Toshiba Electronic Devices & Storage Corporation has added DTMOSVI(HSD), power MOSFETs with high-speed diodes suitable for switching power supplies, including data centers and photovoltaic power conditioners, to its latest-generation DTMOSVI series with a super junction structure. Shipments of the first two products “TK042N65Z5” and “TK095N65Z5,” 650V N-channel power MOSFETs in TO-247 packages, start today.
The new products use high-speed diodes to improve the reverse recovery characteristics important for bridge circuit and inverter circuit applications. Against the standard DTMOSVI, they achieve a 65% reduction in reverse recovery time (trr), and an 88% reduction in reverse recovery charge (Qrr) (measurement conditions: -dIDR/dt= 100A/μs).
The DTMOSVI(HSD) process used in the new products improves on the reverse recovery characteristics of Toshiba’s DTMOSIV series with high-speed diodes (DTMOSIV(HSD)), and has a lower drain cut-off current at high temperatures. The figure of merit “drain-source On-resistance × gate-drain charges” is also lower. The high temperature drain cut-off current of TK042N65Z5 is approximately 90% lower, and the drain-source On-resistance × gate-drain charge 72% lower, than in Toshiba’s current TK62N60W5.
This advance will cut equipment power loss and help to improve efficiency. The TK042N65Z5 shows a maximum improvement in power supply efficiency over the current TK62N60W5 of about 0.4%, as measured in a 1.5kW LLC circuit.
A reference design, “1.6 kW Server Power Supply (Upgraded)”, that uses TK095N65Z5 is available on Toshiba’s website today. The company also offers tools that support circuit design for switching power supplies. Alongside the G0 SPICE model, which verifies circuit function in a short time, highly accurate G2 SPICE models that accurately reproduce transient characteristics are now available.
Toshiba plans to expand the DTMOSVI(HSD) line-up with the release of devices in TO-220 and TO-220SIS through-hole packages, and TOLL and DFN 8×8 surface-mount packages.
The company also will continue to expand its line-up of the DTMOSVI series beyond the already released 650V and 600V products and the new products with high-speed diodes. This will enhance switching power supply efficiency, contributing to energy-saving equipment.
