Thanks very much

hi Katelyn,

appreciate the quick help and feedback
the PMP10532 output seems ok, but the input range is designed for 19~30V

the customer design requirement for the input is 12~24V
I saw another lm5160 design

www.ti.com/.../PMP30227

with the proper input range.
can we use the input design of the PMP30227 and output design of the PMP10532
for the Vin 12~24V Vout +-15V 3W isolated design?
is there anything to watch out for or suggested transformer model?

Thanks very much

Hello,

Yes, this should be alright. The main concern with the PMP15032 is that the EN resistors are setting a turn on voltage of 15V instead of 12V. By redesigning this resistor divider, this device is capable of turning on at 12V.

Best Regards,
Katelyn
