The NCP5602 is a high-efficiency, ultra-small, thinnest white LED driver dedicated to the LCD display backlighting. The built-in DC-DC converter is based on a high efficient charge pump structure with operating mode 1x and 1.5x. It provides a peak 87% efficiency together with a 0.2% LED to LED matching.
The NCP5602 is a dual‑output LED driver designed for LCD backlight applications. It uses a charge‑pump DC‑DC converter that can operate in 1× and 1.5× modes, delivering up to 87 % efficiency and a tight 0.2 % LED‑to‑LED current matching. The device supports I2C programming for output‑current control and includes built‑in short‑circuit, over‑voltage and thermal‑shutdown protection.
Typical specifications include an input voltage range of 2.7 V–5.5 V, up to 30 mA per LED channel (60 mA total), and operation over –40 °C to +85 °C ambient temperature. The chip is offered in a compact LLGA12 2 × 2 mm package and is Pb‑free.
