BPS(Bright Power Semicon) BP1361

The BP1361 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. With few outside components, BP1361 provides a high price performance ratio solution on 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 resistor. The device provides an externally adjustable output current of up to 750mA for a single LED. Using the patent technology, the constant current of LED can be up to ± 3%. A dedicated DIM pin accepts either a DC voltage (0.5V~2.5V) dimming or a wide range of pulsed dimming. Applying a voltage of 0.3V or lower to the DIM pin turns the output off and switches the device into a low current standby state. BP1361 has a build-in power switch, based on different input voltage, BP1361 can drive several 1W or 3W LEDs. The device has the function of thermal shutdown protection and LED short/open-circuit protection. The BP1361 is available in SOT89-5 packages.
