[FAQ] TPS650830: What's the special need for TPS65083x VIN3 and VIN5 Connections?

Part Number: TPS650830

Where should I connect VIN3 and VIN5?

  • Note that it is critical to connect the VIN3/5 to the VIN for the FETs of the respective controller. The VIN3 and VIN5 are used as sense lines to the VIN of the FETs in-order for the high side current limit to work properly. Therefore, be sure to connect them as close as possible to the High Side FET's VIN pad.
