 软件简介 |
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 satisfied 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 the typical application
are sufficient. Additionally, the schottky diode in boost
circuit is integrated in this chip. AP3030 also provides
a disable port 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 to
30V.
The AP3030 is available in standard SOT-23-6 and
TSOT-23-6 packages.
