Note
1:
The integrated MOSFET switches have an integral diode from the L
X
pin to V
IN
and from L
X
to P
GND
. In cases where
these diodes are forward-biased, the package power dissipation limits must be adhered to. Thermal protection is not
able to regulate the junction temperature for these cases.
UVLO is specified for a falling V
IN
. Once the UVLO is activated, the UVLO-
HYS
must be overcome before the device will
return to operation.
