Hi,

LM25037 is ok. I assume it is used in a push-pull, ucc24624 is target LLC so not good for push pull.

Can You suggest the secondary side gate driver for the half-bridge circuit ensures proper switching? Is there any reference available for designing the compensator circuit and Driver circuit for the Half bridge converter using LM25037? The converter specifications are given below.

Vin=30-72V

Vout=12V

Po=400W

Hi,

UCC21225.

Also, if you do not require a automotive grated part, you may consider other half bridge PWM controllers such as LM5036 which has SR drive signals.

If you do need auto motive graded then you would need to find a corresponding one. I am asking since UCC24624 is not a auto motive graded part. So I would suggest considering something like LM5036.

Since we Require for automotive grade, we selected this LM25037.

Drive also we need Automotive grade. and kindly suggest the drive IC which support for our

converter specifications.
