The BD6581GU-E2 from ROHM Semiconductor is a white LED driver IC designed for medium to large LCD panels. It integrates a high-efficiency PWM step-up DC/DC converter capable of boosting up to 42.5V and a current driver that can handle up to 25mA. This device is suitable for applications requiring precise brightness control, which can be achieved via external PWM pulses. The BD6581GU-E2 features highly accurate current drivers with minimal error between strings, helping to reduce brightness spots on LCDs.
Key electrical specifications include a wide input voltage range of 2.7V to 22V and a switching frequency of 1MHz, achieving a maximum efficiency of 93%. It supports both Analog and PWM dimming methods. The IC provides 6 output channels and can drive up to 72 white LEDs. Safety features include over-voltage protection (OVP), over-current limit, external SBD open detection, and thermal shutdown.
Packaged in a small and thin VCSP85H2 (24-VFBGA, CSPBGA) measuring 2.6 x 2.6 x 0.85mm, the BD6581GU-E2 is ideal for space-constrained designs. Its operating temperature range is -30°C to +85°C. This LED driver is well-suited for backlighting in notebook PCs, portable DVD players, and car navigation systems.
