TDK-Lambda adds 60A models to i7A DC/DC converters
The 1/16th brick DC/DC buck converter modules join the company’s existing 33A and 45A models. They have a 400W maximum rating, for 0.8 to 8.0V adjustable outputs from a 12V nominal input. They also introduce the option to adjust the over-current limit on all input voltage and output current models to reduce stress on the converter when exposed to excessive overload conditions. It also helps to fine tune the over-current limit based on actual system needs.
The 60A i7A models can derive additional high power outputs from a 9.0 to 18V DC power supply at a lower cost and higher efficiency than isolated DC/DC converters, said TDK-Lambda. Suitable applications are mobile robotics, drones, medical, industrial, test, measurement, communications, computing and portable battery-powered equipment.
The DC/DC converters are up to 97% efficient and operate in ambient temperatures of -40°C to +125°C, even with low airflow conditions. With minimal external components required, they contribute to reduce the bill of materials compared to discrete solutions, and also lower 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 also available.
All models in the i7A series measure 34mm wide and 36.8mm long and are available with a choice of profiles. The open frame model is 11.5mm high, suitable for low profile applications, while the baseplate version can be conduction cooled to a cold plate and is 12.7mm high and models with an integral heatsink for convection or forced air cooling are 24.9mm high.
All DC/DC converters in the series have safety certification to the IEC/UL/CSA/EN 62368-1 standards, with CE and UKCA marking to the Low Voltage and RoHS Directives.
TDK was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. Its portfolio features passive components such as ceramic, aluminum electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices, as well as sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors, together with power supplies and energy devices marketed under the product brands TDK, Epcos, InvenSense, Micronas, Tronics and TDK-Lambda. TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology. The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
