AP3030KTR全新原装现货，13724201506李生。QQ:2629331408.WHITE LED STEP-UP CONVERTER AP3030
Oct. 2009 Rev. 1. 6 BCD Semiconductor Manufacturing Limited
Data Sheet
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 com-
ponents 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 abnor-
mal conditions, the output voltage will be clamped.
The AP3030 is available in standard SOT-23-6 and
TSOT-23-6 packages.
