Weekly Power Product Recap
This article highlights new products from Recom, Mean Well, Infineon, Toshiba, Traco Power, and Diodes Incorporated.
This product roundup showcases components for several power applications. However, we found a focus this week on power supplies, followed closely by converters.
Open frame AC/DCs Power Supplies From Recom
Recom’s latest addition to its open-frame AC/DC power supplies range, these 2“ x 3” design components feature 90% efficiency across the load range.
The RACM60-K series can operate at full-power in ambient temperatures between -40°C and +55°C without forced cooling, and up to +85°C with derating or forced air.
These AC/DC power supplies also have a universal 80-264VAC input range and various available outputs, including 5V, 12V, 15V, 24V, 36V and 48V.

Featuring full protection against short-circuits, output over-voltage, over-current, and over-temperature, the RACM60-K series is designed for a variety of applications, including audio-visual, industrial and household.
Moreover, the components’ line and neutral fusing make them ideal for medical uses, for which they have been also certified according to ANSI/AAMI/IEC/CSA 60601-1 standards.
The RACM60-K series is already available in various mounting options (including one with cover), and you can request a sample of the components here.
Fanless DIN Rail DC/DC Converter From Mean Well
This new family of DC/DC converters has been developed by Mean Well to enable DIN Rail DC/DC integration into high power applications.
The 480W DDR-480 series builds on Mean Well’s converter product line firstly released in 2018.
The move shows the company’s goal to expand its portfolio towards DC/DC applications like industrial & railway control, security control, and telecommunication systems.
With its 85.5mm-width enclosure, the 480W DDR-480 series is designed to be easily installed onto TS-35/7.5 or 15 standard DIN rails.

The products also come with a series of certifications to enable railway applications, including the EN50155 railway safety standards. In terms of specifications, these DC/DC converters feature 2:1 wide input range, 4000Vdc I/O isolation, and a wide operating temperature range between -40 and 80°C. They also have a 150% peak load capability, current sharing up to 1920W (3+1), and 5G anti-vibration capabilities.
CoolSiC MOSFETs 1700V From Infineon
Adding a new voltage class to its CoolSiC MOSFET family, the 1700 V comes after Infineon’s 650 V class, which was released by the company earlier this year.
The new components are particularly designed for uses in auxiliary power supplies for three-phase conversion systems like renewables, HVDC systems, and motor drives.
According to Infineon, the CoolSiC MOSFETs 1700V series would feature the lowest device capacitances and gate charges for transistors of this voltage class. This would translate into power loss reduction figures of more than 50 percent, as well as 0.6 percent higher efficiency compared to traditional 1700V silicon MOSFETs.

The new series is also optimized for flyback topologies with +12 V / 0 V gate-source voltage compatible with common PWM controllers. Because of this, the components do not require a gate driver IC and can be operated directly by the flyback controller.

Compact Intelligent Power Device From Toshiba
Designed to drive motors of air conditioners, air cleaners, and pumps, these new components by Toshiba have a rated power supply voltage (VBB) of 600V.
Ideal for applications with input signals between 200 and 220VAC, the new power devices feature a PWM circuit, 3-phase decoder, level shifting high-side driver, and low side driver with embedded IGBTs and FRDs. This means they allow direct drive of brushless DC (BLDC) motors with square wave input signals from a Hall sensor or Hall IC without the need for a PWM controller IC.

The new power devices also come with a number of built-in safety features such as current limit, overcurrent protection (OCP), thermal shutdown, and under-voltage lockout (UVLO).
Finally, the components’ small footprint (17.5 x 11.9mm) means they can be installed on boards where space-saving needs are necessary, and directly to the motor.
The power devices are already available on Toshiba’s website, and you can find more about them here.
DC/DC Converters From Traco Power
Designed to offer a low-cost solution while maintaining high-quality standards, these new devices are non-isolated / point-of-load DC/DC converters.
The components come in two different versions, the TSR 1-2433, with 6~36Vin / 3.3 Vout at 1A and the TSR 1-2405E, with 7~36Vin / 5Vout at 1A.
The converters can operate at full load in temperatures up to 60°C, and with high-efficiency rates of up to 92%.

They also feature a 1 Amp output current and various safety features such as low standby current, precise regulation, and short circuit protection.
The components’ input range also makes them ideal for both 12V and 24V bus applications, but Traco Power specified the converters are particularly designed for 5VDC & 3.3VDC output applications in Industrial, Test & Measurement, and IT settings.
Single-Chip Battery Protection Solution From Diodes Incorporated
This single package protection solution is designed for single-cell Li+ rechargeable batteries in portable and wearable devices.
The AP9221 comes with battery protection features such as overcharge voltage/current, over-discharge voltage/current, and load short circuit.

The component also has a built-in fixed delay time feature to minimize false triggering without requiring external timing components.
Available in a U-DFN2030-6 (Type C) package, the AP9221 offers high-voltage CMOS Process capabilities (up to 24V) and Low Quiescent Current (3µA normal; 0.1µA in power down). It also comes with three different Modes: Selectable Power-down Mode, Auto-wake-up Mode, and 0V Battery Charge Mode for maximum design flexibility.
