AP3019AKTR-G1 Description

Short technical summary and product information.

The AP3019AKTR-G1 is an inductor-based DC/DC converter from Diodes Incorporated, specifically designed for driving up to eight white LEDs in series for backlight applications. It utilizes a constant frequency 1.2MHz PWM control scheme, enabling the use of tiny external components like a 1mm tall inductor and a 0.22µF output capacitor.

 

This device integrates the Schottky diode within the boost circuit, simplifying the design and reducing component count. It features inherently uniform LED current control, high efficiency up to 84%, and output over-voltage protection (OVP). The AP3019AKTR-G1 also includes a disable pin for system flexibility and PWM dimming capability for brightness control.

 

Available in a compact TSOT-23-6 package, this LED driver is suitable for applications such as cellular phones, digital cameras, LCD modules, and GPS receivers. It requires a minimum input voltage of 2.5V and can handle a switch current of 550mA.
