ZXLD1320/1321/1322 - LED driver with internal switch

The ZXLD1320/1321/1322 are a range of inductive DC-DC buck, boost and buck / boost converters with an internal switch, designed for driving single or multiple LEDs in series with high efficiency up to 1.5A output current.

    Features
  • Typical efficiency > 80%
  • User-defined thermal control of LED output current using external thermistor
  • High output current stability over input voltage and temperature
  • 12 µA typical standby current
  • Adjustable soft-start
    Applications
  • High power LED flashlights
  • LED back-up lighting
  • General LED lighting
