Description
4
An external capacitor is required between the BST and the
SW pins. A 0.022µF ceramic capacitor is recommended.
The capacitor is charged from Vcc via an internal diode
during the off-time of the buck switch.
Exposed metal pad on the underside of the device. It is
recommended to connect this pad to the PWB ground plane,
in order to aid in heat dissipation.
