New, efficient LED driver from Advanced Power Electronics Corp. suits backlighting applications

Can handle up to eight white LEDs in series; full protection features

August 2013, San Jose, CA … Advanced Power Electronics Corp. (USA), a leading Taiwanese manufacturer of MOS power semiconductors for DC-DC power conversion applications, has launched a new step-up converter capable of efficiently driving up to eight white LEDs in series for backlighting applications. The APE1612-3 uses current mode, 1.2MHz fixed frequency architecture to regulate the LED current, which is set using an external current sense resistor.

The APE1612-3 features a low 300mV feedback voltage that 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 APE1612-3 includes under-voltage lockout, current limiting and thermal shutdown protection preventing damage from an output overload.

Comments Ralph Waggitt, President/CEO, Advanced Power Electronics Corp. (USA): “Small size and high efficiency make the APE1612-3 ideally suited for backlighting applications. A wide 200Hz to 200kHz range enables the device to be used in PWM dimming.

The APE1612TY-HF-3 is shipped in a small RoHS/REACH-compliant TSOT-26 package. More data is available at
