Could MC34844A reach 60V output?

Dear Sirs:

 

I would like to work with the MC34844A under the following requirements:

  • Vin = 12V
  • Vout = 60V
  • Ioutmin = 0,3A
  • Ioutmax = 0,6A
  • For dimming a 3V PWM is using with a variable frequency depending on the specific application.

 

Is is possible to reach such voltaje we made several tests but we never reach more than 47V and we are not sure we can fron the datasheet data.

If 60 V( and current mentioned) are reachable please let me know the values of:

L

Cout

Ccomp1

Ccomp2

Rslope

Rpcomp

Rccomp

 

Thanks in advance
