3PEAK Launches the TPM650xQ Series of High-Performance Automotive Push-Pull Transformer Drivers

3PEAK (stock code: 688536), a semiconductor company focusing on the development of high-performance analog chips and embedded processors, unveiled the TPM650xQ series of high-performance automotive push-pull transformer drivers.

The TPM650xQ series has built-in MOSFETs with a withstanding voltage of 25 V. It can reliably function within a temperature range from –40°C to +125°C. With competitive performance, the TPM650xQ series has been widely used in automotive bus interfaces, industrial instruments, and other terminal areas that require an isolated power supply.
