The FAN5610 is a LED driver chip produced by Fairchild Semiconductor. The chip has a function of driving 4 parallel-connected LEDs, supporting low VF LED low voltage direct lithium-ion battery applications. Each LED has an independent control loop and can provide regulated, matched constant current. The chip has no external components, no EMI and switching noise, and an integrated DAC for digital and PWM brightness control. The maximum efficiency can reach 91%, the maximum bias current can reach 84mA (21mA/LED), the input voltage range is 2.7V to 5.5V, and the shutdown mode current is less than 1µA. The package is 3mmX3mm MLP-8.
The FAN5610 is a 4‑parallel LED driver designed for white, blue, or any color LEDs. It features a low voltage drop (<350 mV), independent current loops for each LED, built‑in DAC for digital and PWM brightness control, and up to 91 % efficiency. The device operates from 2.7 V to 5.5 V input and can drive up to four LEDs with bias currents up to 84 mA (21 mA per LED).\n\nThe datasheet includes pin assignments, absolute maximum ratings, recommended operating conditions, electrical characteristics, mechanical dimensions, and example applications such as single‑cell Li‑ion powered backlights and bus‑voltage driven LEDs. Ordering information and legal notices are also provided.
