40V/1.2A High Dimming Ratio LED Constant Current Driver
GENERAL DESCRIPTION
The BP1371 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 ponents, BP1371 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 resistant. The device provides an...
