PWM solution proposed

Master,

Looking advise on ADI proposal. 

I'm thinking of LTC3890 for Load B (18-24Vdc, Current 5-10A) 
1. Isolated DCDC Converter, Input rated 24Vdc,300W; Output Voltage 18-24Vdc, Current 5-10A                                                                                  
2. PWM Controller Module/Circuit, Input rated 24Vdc,300W; Output Voltage 18-24Vdc, Current 5-10A                                                                                    
3. Current Limiter Module/Circuit, Input rated 24Vdc,300W; Output Voltage 18-24Vdc, Current 5-10A

 I'm thinking of LTC3858 for Load C (8-12Vdc, Current 5-10A)
1. Isolated DCDC Converter, Input rated 12Vdc,100W; Output Voltage 8-12Vdc, Current 5-10A                                                                                   
2. PWM Controller Module/Circuit, Input rated 12Vdc,100W; Output Voltage 8-12Vdc, Current 5-10A                                                                                     
3. Current Limiter Module/Circuit, Input rated 12Vdc,100W; Output Voltage 8-12Vdc, Current 5-10A

 Also LT1950 for this.  

Kindly suggest the suitable parts.

Thanks.
