Part Number: LM96063

Team,

I would like to use LM96063 to control a PWM fan (datasheet attached).

but, the max accuracy is +/-7%.

Is LM96093 suitable for this fan?
Does TI have batter accuracy part than LM96063??

Hi Marco,

Let me have a look.

Marco,

The specs of the fan indicates that it has speed tolerance of ±14.4% (see 30% duty) so I don't see the LM96063's 7% PWM tolerance being much of a limitation. Nor do I see the need for a more precise fan controller based on your information. We do not have that many fan controller products to begin with so our options are limited. If you can give me more detailed system requirements/context maybe I can better help you.
