Hi arash_tah
try with NCP1200, PWM current-mode controller, Fixed frequencies -40kHz, 60kHz and 100kHz,
Vin=30-500Vdc, External MOSFET transistor.
Look at attached file for some additional informations.

Best regards.

Hi arash_tah,
yes, but this circuit is only an idea for your project.
You can change some components to adapt it, like voltage feedback circuit components (for Vout=24V).
MOSFET transistor Q1, current sense resistor R4, diodes D1 and D3, input and output inductors
L1, L2 and L3 (for Iout=10A).

Best regards.
