ROHM Semiconductor USA, LLC LED Drivers BD9470AFM-GE2

The BD9470AFM-GE2 is a high-efficiency LED driver designed for medium to large-sized LCD backlighting applications. It features a 6-channel constant current driver with a maximum output current of 250mA per channel, allowing for individual PWM dimming modulation of the LEDs. The device incorporates a built-in DC-DC converter that supplies the appropriate voltage for the light source and includes several protection functions such as over-voltage protection (OVP), over-current protection (OCP), and short-circuit protection (SCP). The operating voltage range for the BD9470AFM-GE2 is between 9.0V and 35.0V, with an oscillation frequency of 150kHz. It operates effectively across a temperature range of -40¬8C to 85¬8C. The device also features a built-in LED feedback voltage adjustment circuit and a failure indication function, enhancing its reliability in various applications. The package options include HSOP-M28 and HTSSOP-B28, making it suitable for compact designs. This product is particularly applicable for use in TVs, monitors, and other LCD backlighting systems.
