TPS92692-Q1: COMP capacitor

Part Number: TPS92692-Q1

Tool/software:

Hi,

I have question regarding a capacitor for a COMP pin of the TPS92692-Q1. I downloaded the calculation sheet "TPS92692-Q1 Boost Design Calculator" from TI product page. The TPS92692-Q1 has 2 operation mode by DIM/PWM pin and IADJ pin. The question is can we use same capacitor value by the calculation sheet either DIM/PWM or IADJ pin?

Best regards,

Taylor

    Hi Taylor,

    You might be able to, what is the value of the COMP capacitor you calculated? The capacitors at the IADJ and PWM pins are for filtering out noise. I might air on the side of caution and add a variant for the IADJ and PWM capacitors in case you need a more robust filter.

    Best,
