If the Vin were less than +16V, then the Linear Technology LT3471EDD#PBF.LT3471EDD#PBF. could do it.
If no then for +24Vin, you can use 2 x LT3580.

Thanks Mike.
Can I use this IC for ANALOG Circuits power supply without any noise due to ripple voltages.
If done properly yes. Contract your local LTC saels office for help with this design.

Dear Joanathan,
Thanks. But Murata Power supplies are too expensive.
Balakrishna.
You didn't actually mention cost, although you did mention voltage and current.
These devices are very cost-effective when you need a non-engineered solution. I have used them in several custom projects where the production quantity or time-to-market didn't justify the time and expense of R&D for the power supplies. Also, there are generic versions of these devices available from a number of Asian companies at 25-50% of the cost (in quantity). If you are manufacturing thousands of units per month, they probably aren't the correct solution.
The final decision comes down to a lot of factors if you want to engineer the most appropriate solution. Cost is one. Do you have a budget for this section? This answer alone will determine whether you bother to engineer a solution or not.
