DESCRIPTION
An enable input can be pulsed repeatedly to adjust LEDs brightness. Fault condition protection uses cycle-by cycle current limiting to sense maximum inductor current and over-voltage protection. The 0.2V low reference voltage minimized the power loss across the current sense resistor. The converter can operate from 2V to 6V, and capable of delivering maximum 250mA output current at 4-LEDs application with 3V input voltage is as low as 120uA. All of these features make ACE714C be suitable for the portable devices, which are supplied by a single battery. Featur
