Semtech Corporation SC4539ULTRT is a highly efficient DC-DC boost LED driver IC designed for backlight applications. This single-output device features a step-up topology, capable of delivering a regulated output voltage ranging from 5V to 22V with a maximum output current of 30mA per channel. The SC4539ULTRT incorporates integrated switching circuitry and supports Pulse Width Modulation (PWM) dimming for precise brightness control. Operating at a switching frequency of 800kHz, it offers a compact solution in an 8-MLPD-UT (2x2) surface-mount package. The device operates within a supply voltage range of 2.8V to 5.5V and is specified for operation from -40°C to 85°C. This component is ideal for power-sensitive portable electronics and display backlighting systems.
