LMZM23600: How to reduce delay between EN and Vout of LMZM23600

user5825527

Part Number: LMZM23600

I read an answer to one of the customers question regarding time EN and Vout ,the delay between EN and Vout at Il=0.25A,V out= 5.0v is approximately 5ms. i am using  LMZM23600 as a replacement design to an existing design. LMZM23600 is quite apt for me because of its small size with given i/p and o/p specs. because of 5ms delay  built in test  is failing. is there any way i can reduce this delay? All i/p and o/p caps as suggested. linear regulator is hogging current because of low efficiency. pls advice.

regards

    Hi,

    Can you explain to me what you are doing in your testing and what is your key concern during your built in test that is failing? If you have a schematic, can you please attach it for me to look at for reference. What is the LMZM23600 loading? By any chance are you sequencing the LMZM23600 with a linear regulator at the output?

    I've attached the E2E post that I answered on the EN and VOUT delay time for reference.

    Regards,
