48Vin to 150Vout boost circuit with adjustable boost current control

Hope that someone could help me with which device is best to use for the following boost circuit application.

- input voltage is +48V with ±4V tolerance.

- output voltage is 160V

- Boost current should be firmware adjustable through analog voltage and should not exceed input current of 3A or 6A (two different configurations)

- Enable / Disable of boost circuit

- Small footprint and high efficiency will be nice.

LT Power CAD does not help much with this requirement.

I looked at the LT3756 which may be an option as the load will be in place of the LED string and the PWM FET is not required.

Are there any other devices that may be a better fit for this application which I have overlooked.
