AP3019 Datasheet (BCD Semiconductor) - WHITE LED STEP-UP CONVERTER

AP3019, 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 control the LED current and obtain satisfied brightness.

A constant frequency 1.0MHz PWM control scheme is employed in this IC, which means the tin
