Description

Description
The ZXLD1366 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 6V and 60V and provides an externally adjustable output current of up to 1A. Depending upon supply voltage and external components, this can provide up to 48 watts of output power.
The ZXLD1366 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
Features
• Typically better than 0.8% output current accuracy
• Available in thermally enhanced DFN package
• Simple and with low part count
• Single pin on/off and brightness control using DC voltage or PWM
• PWM resolution up to 1000:1
• High efficiency (up to 97%)
• Wide input voltage range: 6V to 60V
• Inherent open-circuit LED protection
Applications
• Low voltage halogen replacement LEDs
• Automotive lighting
• Low voltage industrial lighting
• LED back-up lighting
• Illuminated signs
• Emergency lighting
• SELV lighting
• LCD TV backlighting
• Refrigeration lights
