Half-bridge controller: Vin = 400V

Other Parts Discussed in Thread: UCC28250, UCC28083

Hi

 

i am seeking a pwm controller for an isolated half-bridge.

IT is for powering class d guitar amp so huge output transients and overloads occur.

 

-as such, overload protection will not be required or must be bypassed.

 

power is 140W,  but as i said there will be short term overloads........and vout will sag

 

i will put overcurrent limiting on output

 

vout = +-35V
