AP3019A Datasheet White Led Step-up Converter

Manufacturer: Diodes Incorporated

Overview: NEW PRODUCT AP3019A WHITE LED STEP-UP CONVERTER.

General Description

The AP3019A is an inductor-based DC/DC converter designed to drive up to eight white LEDs in series for backlight.

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

Pin Assignments (Top View) Pin 1 Mark A constant frequency 1.2MHz PWM control scheme is employed in this IC, which means tiny external components can be used.

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 0.22F Output Capacitor SW 1 GND 2 FB 3 6 VIN 5 VOUT 4 CTRL K/KT Package (SOT-23-6/TSOT-23-6).
