AX2012 1.9A Fixed Frequency White LED Driver

AX2012 Description

AX2012 1.9A Fixed Frequency White LED Driver  GENERAL .
The AX2012 is a step-up converter designed for driving up to 8 series white LEDs for backlighting application.

AX2012 Features

* 2.5V to 5.5 V operating input voltage range Drives up to 8 series White LEDs 1.2MHz Fixed Switching Frequency Wide range for PWM dimming Ñb€ (200Hz to 200KHz) y
* R ` Internal 1.9A switching w current limit m Û V Over Voltage Protection (OVP) . com h Internal Soft-start Functiontec o of shutd

AX2012 Applications

* is sufficient. For a lower output power requirement application, this value can be decreased. The output capacitor is required to keep the output voltage ripple small and to ensure regulation loop stability. The output capacitor must have low impedance at the switching frequency. Ceramic capacitors
