The AP3036/A is a 1 MHz step‑up LED driver that powers up to eight white LEDs with high efficiency.
The AP3036/A is an inductor‑based DC/DC converter designed for white LED backlight applications. It drives up to eight LEDs in series, uses a fixed 1.0 MHz PWM switching scheme, and requires only a tiny inductor and a 0.22 µF output capacitor. The device includes an integrated Schottky diode, a disable pin, and output over‑voltage protection.
The converter is offered in standard SOT‑23‑6 and TSOT‑23‑6 packages. Electrical specifications include an input voltage range of 2.5 V to 16 V, a switching frequency of 1 MHz, and efficiency up to 84 %. Typical applications are cellular phones, digital cameras, LCD modules, GPS receivers, and handheld computers.
