onsemi LED Drivers FAN5343UMPX

The FAN5343UMPX is an asynchronous boost LED driver designed to efficiently power up to six LEDs in series, delivering a maximum output power of 500mW. It operates within an input voltage range of 2.7V to 5.5V and can provide an output voltage of up to 24V. The device features a single-wire digital control interface that allows for brightness adjustment in 32 linear steps through digital pulses. Key protective features include input under-voltage lockout, output over-voltage protection, short-circuit detection, and thermal shutdown protection, ensuring safe operation in various applications. The FAN5343UMPX is housed in a compact 6-lead UMLP package measuring 2.0mm x 2.0mm x 0.55mm, making it suitable for space-constrained designs such as cellular mobile handsets, portable media players, and mobile internet devices.
