AS1343
Datasheet - Application Information
LED Power Supply Application
The AS1343 can also be used for driving LEDs. Just simply connect the LEDs between the pins V
OUT
and FB.
(see
Figure 29)
.
Figure 29. LED Supply Application
The output voltage is adjusted automatically to the required voltage of the LEDs. This voltage depends on the forward
voltage (V
F
) of the used LEDs and the Feeback Voltage V
FB
.
Calculate V

by:
Note:
The brightness of the LEDs can directly be adjusted by setting the current I
LED
via the corresponding R

Thermal Protection
To protect the device from short circuit or excessive power dissipation of the auxiliary NPNs, the integrated thermal
protection switches off the device when the junction temperature (T
J
) reaches 140oC (typ). When T
J
decreases to
approximately 135oC, the device will resume normal operation. If the thermal overload condition is not corrected, the
device will switch on and off while maintaining T
J
within the range between 135 and 140oC.
