onsemi LED Drivers FAN5624UMPX

The FAN5624UMPX is a four-channel linear LED driver designed for mobile electronics applications, such as backlighting for LCD displays and keypads. It features a maximum output current of 30 mA per channel and operates with a low dropout voltage of 50 mV at 15 mA, allowing for efficient LED driving without the need for inductors or switch capacitors. The device supports a single-wire digital control interface, enabling users to program 32 linear dimming steps and control the on/off state of the LEDs through digital pulses. This LED driver integrates essential protection features, including short-circuit, under-voltage, and thermal protection, enhancing its reliability in various applications. The operating input voltage range is from 2.7 V to 5.5 V, and it is available in a compact 10-lead ultrathin molded leadless package (UMLP), making it suitable for space-constrained designs. The FAN5624UMPX is a Pb-free device, aligning with environmental standards.
