Texas Instruments New Portfolios Redefine Power Design Limits

Texas Instruments New Portfolios Redefine Power Design LimitsTexas Instruments has introduced two new power conversion device portfolios to help engineers achieve more power in smaller spaces, providing the highest power density at a lower cost. TI’s new 100V integrated gallium nitride (GaN) power stages feature thermally enhanced dual-side cooled package technology to simplify thermal designs and achieve the highest power density in mid-voltage applications at more than 1.5kW/in3. TI’s new 1.5W isolated DC/DC modules with integrated transformers are the industry’s smallest and most power-dense, helping engineers shrink the isolated bias power-supply size in automotive and industrial systems by over 89%. Devices from both portfolios will be on display at this year’s Applied Power Electronics Conference (APEC), Feb. 25-29 in Long Beach, California.

“For power-supply designers, delivering more power in limited spaces will always be a critical design challenge,” said Kannan Soundarapandian, general manager of High Voltage Power at TI. “Take data centers, for example – if engineers can design power-dense server power-supply solutions, data centers can operate more efficiently to meet growing processing needs while also minimizing their environmental footprint. We’re excited to continue to push the limits of power management by offering innovations that help engineers deliver the highest power density, efficiency and thermal performance.”

With TI’s new 100V GaN power stages, LMG2100R044 and LMG3100R017, designers can reduce power-supply solution size for mid-voltage applications by more than 40% and achieve industry-leading power density of over 1.5kW/in3, enabled by GaN technology’s higher switching frequencies. The new portfolio also reduces switching power losses by 50% compared to silicon-based solutions, while achieving 98% or higher system efficiency given the lower output capacitance and lower gate-drive losses. In a solar inverter system, for example, higher density and efficiency enables the same panel to store and produce more power while decreasing the size of the overall microinverter system.

A key enabler of the thermal performance in the 100V GaN portfolio is TI’s thermally enhanced dual-side cooled package. This technology enables more efficient heat removal from both sides of the device and offers improved thermal resistance compared to competing integrated GaN devices.
