TPS61196: TPS61196 EN/PWM pin input current

Kevin Wen

Part Number: TPS61196

Hi team,

would you please suggest the input current requirement? if customer need to use 1 GPIO to control 40 PWM input pins of TPS61196, how much current is needed to draw from GPIO? Thanks.

Hi Kevin,
The pull-down resistance on EN/PWMx pins are from 0.8M to 3M. And the minimal logic high input on EN/PWMx is 1.8V. So the minimum current for EN/PWMx is 1.8V/0.8M=2.25uA. So please be careful with this application.
