BELLING BL9580

The BL9580 is a continuous mode inductive Internal 36V NDMOS switch Up to 1.4A output current step-down converter, designed for driving Step-DowsninCgleonorvemrutlteiprle series connected LEDs Single pin on/off and brightness control using DC voltage or PWM efficiently from a voltage source higher than, the LED voltage. The device operates from Soft Start an input supply between 6V and 36V and High efficiency (up to 97%) provides an externally output current up to Wide input voltage range: 6V to 36V 1.4A. Inherent open-circuit LED protection The BL9580 includes the output switch and a Typical 3% output current accuracy high-side output current sensing circuit, which High-side current sense uses an external resistor to set the nominal Hysteretic control: no compensation average output current.
