AX2012CTA

1.9A Fixed Frequency White LED Driver

axelite目前产品线主要包括：DC-DC电源转换IC (Power Converter IC)、

DC-DC电源控制IC (Power Control IC)、LED电源驱动IC (LED Power Devices

IC)、LDO与其他电源IC (LD Power Devices & MOSFET)。

axelite 概要：

The AX2012CTA is a step-up converter designed for driving up to 8 series white

LEDs for backlighting application. The AX2012CTA uses current mode,

1.2MHZ fixed frequency architecture to regulate the LED current, which is set

through an external current sense resistor. Its low 300mV feedback voltage reduces

power loss and improves efficiency.

The OV pin monitors the output voltage and turns off the converter if an over-voltage

condition is present due to an open circuit condition. The AX2012CTA includes

under-voltage lockout, current limiting and thermal shutdown protection

preventing damage in the event of an output overload. The driver is available in

small 6-pin TSOT-23 and 8-pin TDFN (2mm x 2mm)

packages.
