Place output capacitors as close as possible to VOUT VOUT 1 Power and PGND. For thermal performance, use copper plane(s) at this pin. Power good flag pin. This open drain output is pulled up if the feedback PG 2 Output voltage is greater than 95% or less than 105% of the internal reference voltage. A pull-up resistor is required if this function is used. Feedback pin. This pin must be connected to the external resistor FB 3 Input divider (between VOUT and PGND) to adjust the output voltage. Input voltage. Place the input capacitor as close as possible to VIN VIN 4 Power and PGND. Enable pin. Setting this pin high enables the device, while setting this EN 5 Input pin low shuts down the device. This pin must not be left floating. Power ground. It must be connected to the ground plane and to the PGND 6 Power thermal pad. Exposed pad. This pin is internally electrically connected to PGND. It Exposed PGND EP is recommended to connect it to the ground plane for device heat Pad dissipation. Data Sheet version 2.0 November 2021 www.we-online.com/powermodules 2
