Rohm Semiconductor BD81A34MUV-ME2 is a versatile DC-DC controller for LED driving applications. This component features four independent output channels, each capable of driving up to 120mA. It supports both step-down (buck) and step-up (boost) topologies, offering flexibility in power management. The device integrates Pulse Width Modulation (PWM) dimming for precise brightness control, operating with a frequency range of 200kHz to 2.2MHz. Designed for surface mounting, it is supplied in a 28-VFQFN Exposed Pad package (VQFN28SV5050) on tape and reel. The operating voltage range spans from 4.5V to 35V, with a maximum output voltage of 40V. This driver is particularly suited for backlight applications in consumer electronics and automotive systems.
