AP3030 - WHITE LED STEP-UP CONVERTER

General Description

The AP3030 is an inductor-based DC/DC converter designed to drive up to eight white LEDs in series or 2 rows of LEDs with 5 for each in parallel for backlight.

Only one feedback resistor is needed to control the LED current and obtain required brightness.

Key Features

  • Inherently Uniform LED Current High Efficiency up to 84% No Need for External Schottky Diode Output Over-Voltage Protection (OVP) Fixed 1.2MHz Switching Frequency Uses Tiny 1mm Tall Inductor Requires Only 0.22µF Output Capacitor.

Data Sheet WHITE LED STEP-UP CONVERTER General Description The AP3030 is an inductor-based DC/DC converter designed to drive up to eight white LEDs in series or 2 rows of LEDs with 5 for each in parallel for backlight. Only one feedback resistor is needed to control the LED current and obtain required brightness. A constant frequency 1.2MHz PWM control scheme is employed in this IC, which means tiny external components can be used. Specifically, 1mm tall inductor and 0.22µF output capacitor for a typical application are sufficient. Additionally, the schottky diode in boost circuit is integrated on this chip. AP3030 also provides a disable pin to ease its use for different systems. The output over-voltage protection is implemented in AP3030.
