TPS1H100-Q1: is there any Solution for 32V/5A application？

Hi,

The TPS1HB16-Q1 may fit your solution needs. Assuming no PWM and a constant 5A load, the junction temperature would increase by about 32C. If the ambient temperature is about 100C, this would be fine. With the voltage you’ve given, the 32V does work though short-circuit protection is not guaranteed.

What is the application that you’re using it for? Is it automotive or industrial? We may be able to provide a more viable solution if we also understood the load characteristics such as resistance, capacitance, and inductance.

TKS for your reply。Acturally It is a  Medical rehabilitation product，the load is inductance coil，and it will work in PWM mode。I appreciate your futher reply.

Hi,

Alrighty, would you be able to provide the inductance of the coil and PWM characteristics (frequency, duty cycle)? That'd be helpful in figuring out thermal swings based on the device.

Hi Anthony :

        The PWM duty would be 0~60%,the Frequency would be 0.5Hz~100Hz, .I don't have  a  complete data about the inductance of the coil,it would be a range about  15uH,and its DCR is 8 ohm

Thank you for your support sincerely
