Tool/software:
Hello,
For our HMI project, we are using LM5157 to supply LCD
Vin:5V
Vout: 12V 1A max
Schematic is attached
at EVM and Webench 1.5uH inductor is used. We decided to use 2.2u inductor (SRP1265A-2R2M) to reduce BOM.
Is this inductor suitable for operation?
Additionally, for the Schottky diode we are using SS520FSH is it okay?
Cin at 5V (derated value) is total 45u and Cout at 12V (derated value) is total 25u. Is it okay?
Additionally, we shall use an enable pin with logic input. Can we do that? Can we choose R262 as 0R instead of 100k and R265 as 100k instead of 61K9?
Best regards,
Egemen Aksoy
