New Industry Products

Buck Converters, AC-DC Converters, and DC-DC Converters

July 29, 2020 by Alessandro Mascellino

In this month’s power converters product recap we take a look at converters from Diodes Incorporated, Brightloop Converters and GaN Systems, EPC/ Microchip, and Mornsun.

This recap showcases several power converter products for different applications, including pHeading 5oint of load (POL), electric motorsport and aerospace, data centers, and thermal designs.

Low Voltage Automotive Buck Converter from Diodes Incorporated

The AP61100Q was developed for automotive applications such as infotainment systems, instrumentation clusters, telematics, and advanced driver assistance systems (ADAS).

The new buck converter is a 5.5V, 1A continuous output current, synchronous buck converter designed for POL applications.

The component has a fully integrated 110mΩ high-side power MOSFET and 80mΩ low-side power MOSFET, thus providing high-efficiency step-down DC-DC conversion from 5V and 3.3V input rails.

The AP61100Q features a multi-functional programmable EN pin that allows the device to operate either in forced pulse width modulation (PWM) or in pulse frequency modulation (PFM).

The buck converter offers an output voltage range of 0.6V to 3.6V and operates at 2.2MHz. It is also AEC-Q100 Grade 1-qualified and supports PPAP documentation.

AC/DC and DC/DC Converters From GaN Systems and BrightLoop Converters

The latest collaboration between GaN Systems and French power electronics company BrightLoop Converters, these new converters were created for electric motorsport and aerospace applications.

The devices utilize GaN Systems’ 650V GaN transistors and BrightLoop converters’ technology to create components that are small, light, and efficient.

In fact, BrightLoop’s most recent family of DCDC converters include the 1.9kW, 4.8kW, and 9.6kW DCDC converters incorporate GaN Systems transistors.

This makes the components around half the size and weight of BrightLoop’s first-generation DCDC converters which were developed without GaN.

The company’s DCDC converters are already used in many of the Formula E teams, and BrightLoop said it will unveil a high-performance 5kW ACDC power factor correction (PFC) product for aerospace applications next year.

Additional details about the GaN Systems and BrightLoop Converters collaboration can be found in this case study on Gan Systems’ website.

 

DC-DC Converter Demonstration Board From EPC and Microchip

Another interesting collaboration this month is the one between EPC and Microchip.

The companies worked together to release the EPC9143 DC-DC converter demonstration board, a 300 W DC-DC voltage regulator in 16th brick size.

The device utilizes Microchip’s dsPIC33CK digital signal controller (DSC) and the latest generation EPC2053 eGaN FETs from EPC to achieve 96% efficiency in a 48 V input to 12 V output conversion at 25 A. 

The EPC9143’s switching frequency of 500 kHz enables 300 W in compact housing of 33 mm x 22.9 mm (1.3 x 0.9 in).

The device’s input voltage to be adjusted from 8 V – 72 V and the output voltage from 3.3 V – 25 V and additional phases can be added to further increase power.

The EPC9143 demonstration board is already available for $378.00 and you can buy it from Digi-Key here.

 

AC-DC Converters From Mornsun

The latest collaboration between GaN Systems and French power electronics company BrightLoop Converters, these new converters were created for electric motorsport and aerospace applications.

The devices utilize GaN Systems’ 650V GaN transistors and BrightLoop converters’ technology to create components that are small, light, and efficient.

Both primary and secondary sides of the LOF series meet the reinforced insulation with 2*MOPP, and their isolation voltage is up to 4000VAC.

The new components feature a universal input range of 85 - 264VAC/120 - 370VDC and operation temperature between -40℃ and 85℃.

They also meet a variety of industry standards including EC/EN/UL 62368、IEC/EN 60335、GB4943、IEC/EN/ES60601 and IEC/EN61558.
