AP3019AKTTR-G1 Description

Short technical summary and product information.

The AP3019AKTTR-G1 from Diodes Incorporated is an inductor-based DC/DC converter specifically designed for driving up to eight white LEDs in series for backlight applications. It employs 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.

 

Key features include inherently uniform LED current, high efficiency up to 84%, and integrated Schottky diode, eliminating the need for an external component. The device also offers output over-voltage protection (OVP) and a disable pin for system flexibility. It supports PWM dimming for brightness control.

 

This converter is available in a compact SOT-23-6 Thin and TSOT-23-6 package, suitable for surface mount applications. Its typical applications include cellular phones, digital cameras, LCD modules, GPS receivers, and PDAs, where efficient LED backlight driving is required.
