Overview
Step-Up DC/DC Converters for White LED Backlight Applications General Description The AAT1231/1231-1 are high frequency, high efficiency constant current boost converters capable of 24V maximum output voltage.
Both devices are ideal power solutions for backlight applications with up to six white LEDs in series or up to twelve white LEDs in a parallel/series configuration.
The input voltage is 2.
7V to 5.
5V for single-cell lithiumion/polymer (Li-ion) based portable devices.
The LED current is digitally controlled across a 6x operating range using AnalogicTech’s Simple Serial Control™ (S2Cwire™) interface.
Programmability across 26 discrete current steps provides high resolution, low noise, fli...
