Functional Description

The AAT1231 and the AAT1231-1 consist of a

DC/DC boost controller, an integrated slew rate

controlled input disconnect MOSFET switch, and a

high voltage MOSFET power switch. A high voltage

rectifier, power inductor, output capacitor, and

sense resistors are required to implement a DC/DC

constant current boost converter. The input discon-

nect switch is activated when a valid input voltage

is present and the EN/SET pin is pulled high. The

slew rate control on the P-channel MOSFET

ensures minimal inrush current as the output volt-

age is charged to the input voltage, prior to the

switching of the N-channel power MOSFET.

Monotonic turn-on is guaranteed by the integrated

soft-start circuitry. Soft-start eliminates output volt-

The maximum current through the LED string is set

by the ballast resistor and the feedback voltage of

the IC. The output current may be programmed by

adjusting the level of the feedback reference volt-

age which is programmed through the S²Cwire

interface. The SEL pin selects one of two feedback

voltage ranges. For the AAT1231 and with a LOW

logic level applied to the SEL pin, the FB pin volt-

age can be programmed from 0.1V to 0.4V. With a

logic HIGH applied to the SEL pin, the FB pin volt-

age can be programmed from 0.3V to 0.6V. In the

AAT1231-1, the SEL function is inverted in that the

FB pin voltage can be programmed from 0.4V to

0.1V with a logic LOW applied to the SEL pin and

0.6V to 0.3V with a logic HIGH applied to the SEL
