| Data Sheet WHITE LED STEP-UP CONVERTER General Description AP3030 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. When any LED is broken or in other abnormal conditions, the output voltage will be clamped. The AP3030 is available in standard SOT-23-6 and TSOT-23-6 packages. • 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 • Cellular Phones • Digital Cameras • LCD modules • GPS Receivers • PDAs, Handheld Computers SOT-23-6 TSOT-23-6 Figure Package Types of AP3030 BCD Semiconductor Manufacturing Limited 1 WHITE LED STEP-UP CONVERTER Pin Configuration K/KT Package SOT-23-6/TSOT-23-6 Pin 1 Mark SW 1 GND 2 6 VIN 5 VOUT 4 CTRL Figure Pin Configuration of AP3030 Top View Data Sheet AP3030 Pin Description Pin Number 1 2 3 Pin Name SW GND FB CTRL VOUT VIN Function Switch Pin.
