BP1360

BP1360 30V/500mA High Dimming Ratio LED Constant Current Driver GENERAL DESCRIPTION The BP1360 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the total LEDs chain voltage. Using a few external components, BP1360 provides a high cost effective solution to the following applications: MR16 LEDs cup lighting, LEDs stage lighting, LEDs automotive lighting, LEDs solar lighting and LEDs Street lighting. The device operates from an input supply between 5V and 30V and the nominal average output current is set by an external current sense resistor. The device provides an externally adjustable output current of up to 500mA for a single LED. Using the patent pending technique, the accuracy of constant LED current can be within ± 3%. A dedicated DIM pin accepts either a DC voltage (0.5V~2.5V) dimming or a wide range of pulsed dimming. Applying a voltag...
