uc3856 slope compensation

Intellectual 580 points
Other Parts Discussed in Thread: UC3856

HI,

 

I am working on a push pull converter wich should operate from a 48V dc bus.

I intend to use UC3856 currentmode pwm or similar.

There is an absolute need for external syncronisation, which can be accomplished

by grounding the CS pin and applying external sync signal. But how do I implement slope compensation

in this situation,  where the CS ramp signal is tied to ground?

 

regards

Geert de Vries
