The CAT3649HV3-GT2 from ON Semiconductor is a high-efficiency fractional charge pump LED driver capable of driving up to six LEDs. It supports multiple charge pump modes including 1x, 1.33x, 1.5x, and 2x, offering power efficiency up to 92%.
This device operates with an input voltage range of 2.4 V to 5.5 V and can deliver up to 25 mA per channel. It provides 32 linear dimming steps via a 1-wire input (ADIM) and further adjustment through a PWM signal with frequencies up to 200 kHz, making it compatible with content adaptive brightness control (CABC).
The CAT3649HV3-GT2 is designed for applications such as LCD display backlights in cellular phones, digital still cameras, and handheld devices. It features soft start, current limiting, short circuit protection, and thermal shutdown protection for reliable operation.
The LED driver is housed in a compact 3 mm x 3 mm, 16-pad TQFN package, suitable for surface mount applications. It is Pb-free, Halogen Free/BFR Free, and RoHS compliant.
