Part Number: TPS51219
Other Parts Discussed in Thread: TPS51716

Hello

1. Customer use TPS51219 design tool, the value is calculated 25.8A. What is the several times the output current ?

2. Per TPS51716, OCP (PR152) would like to be decreased 1.5 times to output current. What is the suggested value? Thank you.

Hello Patrick,

Usually, we set the OC value as 1.5 times max loading. Then we can calculate CS resister according to datasheet page 19.

1: what's the max loading? if you know the max loading, it's easy to calculate the times.

2:if you want to calculate the CS resister, please tell me Vin, Vout, frequency, inductor, and max loading.

best regards,

edwin,
