Pinning information

7.1 Pinning

7.2 Pin description

[1]

Connect a decoupling capacitance with a minimum value of 0.1

F as close as possible to the input VIN.

Functional description

[1]

H = HIGH voltage level; L = LOW voltage level.

(1) This pad is not a supply pin. The substrate is attached to

the pad using conductive die attach material. It is used

for heat sink purpose. The solder land should be

connected to GND.
