The CAT3626HV4-GT2 from ON Semiconductor is a high-efficiency, 1x/1.5x fractional charge pump LED driver designed for applications requiring precise current regulation across six LED channels. It offers programmable dimming current up to 32 mA per channel with 0.5 mA resolution, controlled via an I2C serial interface.
This device operates with a fixed switching frequency of 1 MHz, enabling the use of small external ceramic capacitors and minimizing input ripple. It supports a wide input voltage range of 3 V to 5.5 V, making it suitable for Li-Ion battery-powered devices. The LED channels are configured into three independent pairs, allowing for separate current programming.
Key features include soft start, current limiting, short circuit protection, and thermal shutdown protection. The device enters a zero current shutdown mode when the enable input is low. It is available in a 16-pad TQFN package with a maximum height of 0.8 mm, suitable for surface mounting.
Applications include RGB LEDs, LCD and keypad backlighting in cellular phones, PDAs, and digital cameras.
