Switching regulator for 24Vdc to 5Vdc at 2Amps

[techie]

What is the most suitable switching regulator for 24Vdc to 5Vdc @ 2Amps. Isolation is not required, regulation can be +/- 10%. Ripple is also not a problem.

The MAX 724 is a good choice!

Re: 24vDC to 5vDC @2A

is there a situation that transistor(power) in LM2576 become short circuit and inputs goes to output directly(overvoltage?

Where can I find Overvoltage circuit?

Make a search for “crowbar circuit” and you will find what you need!

Look at the AP1501 from Anachip....very low cost and easy to work with.

VIN up to 24VDC in and Vout down to 1.2 VDC

Look at h**p://www.micrel.com/

The MIC4684 is a high-efficiency 200kHz stepdown (buck) switching regulator. Power conversion efficiency of above 85% is easily obtainable for a wide variety of applications. The MIC4684 achieves 2A of continuous current in an 8-lead SO (small outline) package at 60°C ambient temperature.
