PRODUCT UPDATE 29 www.power-mag.com Issue 3 2023 Power Electronics Europe transient immunity of ±100V/ns over the full temperature range to guard against unwanted transistor gate change. The STGAP2GS is available with separate sink and source pins for tuning the gate driving operation and performance. It also has a built-in system protection including thermal shutdown and under-voltage lockout (UVLO) optimised for GaN technology, to ensure reliability and ruggedness. There is no need for discrete components to provide optical isolation, says the company. The company believes the driver can introduce GaN technology in a range of consumer and industrial applications such as power supplies in computer servers, factory-automation equipment, motor drivers, solar and wind power systems, home appliances, domestic fans, and wireless chargers. Two demonstration boards, the EVSTGAP2GS and EVSTGAP2GSN, combine the standard STGAP2GS and narrow STGAP2GSN with ST’s SGT120R65AL 75mΩ, 650V enhancement-Mode GaN transistors to help users evaluate the drivers’ capabilities. The STGAP2GS in SO-8 widebody package, and the STGAP2GSN SO-8 narrow version, are available now. They have a 400W maximum rating, offering 0.8 to 8.0V adjustable outputs from a 12V nominal input. There is now the option to adjust the over-current limit on all input voltage and output current models. This feature helps reduce stress on the converter when exposed to excessive overload conditions and also helps to fine tune the over-current limit based on actual system needs, says the company. The 60A i7A models can be used to derive additional high-power outputs from a 9.0 to 18V DC power supply at a lower cost and higher efficiency than Models with adjustable current limit expand i7A series of DC/DC converters isolated DC/DC converters. The compact modules are suitable for mobile robotics, drones, medical, industrial, test, measurement, communications, computing and portable battery-powered equipment. Efficiencies are up to 97% and the DC/DC converter operates in ambient temperatures of -40°C to 125°C, even with low airflow conditions, says TDKLambda. In addition to low output ripple and response to dynamic loads, the modules have a lower bill of materials compared to discrete solutions, with minimal external components required, according to the company. This saves both cost and PCB space requirements. The i7A 60A standard features include output voltage adjustment, remote sense, negative logic remote on-off, input under-voltage, over-current and over-temperature protection. Evaluation boards are available for simplified qualification. The 60A version joins the existing 33A and 45A models. All measure 34mm wide and 36.8mm long with a choice of profiles. The open frame model at 11.5mm high is suitable for applications requiring a low profile. The baseplate version can be conduction cooled to a cold plate and is 12.7mm high. Models with an integral heatsink for convection or forced air cooling are 24.9mm high. All models have safety certification to the IEC/UL/CSA/EN 62368-1 standards, with CE and UKCA marking to the Low Voltage and RoHS Directives.
