WHITE LED STEP-UP CONVERTER

The AP3019 is an inductor-based DC/DC converter designed to drive up to five white LEDs in series for backlight. Only one feedback resistor is needed to con- trol the LED current and obtain satisfied brightness. A constant frequency 1.0MHz PWM control scheme is employed in this IC, which means the tiny external components CAN be used. In fact, 1mm tall inductor and 0.22F output capacitor for the typical application is very appropriate. Additionally, the Schottky Diode in boost circuit is integrated in this chip. AP3019 also provides a disable port to ease its use for different sys- tems. The over output voltage protection is equipped in AP3019. When any LED is broken or in other abnor- mal conditions, the output voltage will be clamped to 27V. By BCD Semiconductor Manufacturing Limited
