STSPIN958 as a full bridge digital adjustable PSU

Dear all,

 

The STSPIN958 contains all to build a digital controlled (hard switching) full bridge adjustable power supply, including the power mosfets, to my understanding. Or am I missing something important?

 

If set as " Single full-bridge - PWM trimming", given a 200kHz PWM signal on PWM1 and the inverted PWM signal on PWM2/PH. With adjusting Vref, the pulse width and so the output voltage can be adjusted. By adjusting the PWM pulse width, the current limit could be set.  Could I test this with the EVSPIN958 and a Pulse PA3856.007NL forward transformer? 

The chip is presented as motor driver, a use as PSU is not mentioned. Would be great when somebody could confirm (or tell my why not) it could be used as a PSU as well.

 

Thanks,

Michi
