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,
