TPS65233: Reference design questions

david abrams

Part Number: TPS65233

How do you calculate the main inductor value and its current capability if we set output current to 500mA.

What is purpose of D131/D132 on TPS65233EVM schematic and what is their specific characteristic need in the circuit.

Hi David,

I moved the post to non-isolated DC/DC to try to ensure that you have access to proper support.

Hi,

D131/D132 is used for surge test.

D131 should be Schottky diode, you can select B240A-13-F.

D132 should be TVS diode, you can select SMCJ28A.

just for your reference.

thanks.
