SOP8 Name Description 1 SW SW is the switching node that supplies power to the output. Connect the output LC filter from SW 2 BST Bootstrap pin for top switch. A 0.01uF or larger capacitor should be connected between this pin 3 VD Output of the internal LDO. A capacitor of 2.2uF or larger should be connected at VD to ground. 4 FB Output feedback pin. FB senses the output voltage and is regulated by the control loop to 0.8V. 5 NC 6 NC 7 EN Drive EN pin high to turn on the regulator and low to turn off the regulator. 8 VIN Input voltage pin. VIN supplies power to the IC. Connect a 3.6V to 40V supply to VIN and bypass 9 GND Ground. Item Symbol Condition Min. Typ. Max.
