The ZXLD1320DCATC is a Buck mode DC-DC converter. It includes an internal switch, designed for driving single or multiple LEDs in series up to a total of 1.5 A output current.

This device employs a variable 'on' and 'off' time control scheme with adjustable peak switch current limiting and operates in the step-down (Buck) operating mode, offering higher power efficiency and lower system cost than conventional PFM circuitry.


  • Step-down LED driver
  • 4 V to 18 V input voltage range
  • Typical efficiency > 85%
  • 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
  • LED current adjustable from 100 % down to 2 %
  • Adjustable soft-start
  • Capable of driving 4 LEDs in series


  • Low voltage halogen lamp replacement with LEDs
  • High power LED flashlights
  • LED back-up lighting
  • General LED lighting
  • Automotive lighting
