  • Circuit Ideas: How to Parallel LED Current Drivers
    As white LEDs become more pervasive, there are ever-more options for driving them. Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If power dissipation
  • Increase the Number of Series White LEDs with a "Constant Voltage" OVP Circuit
    A unique over-voftage protection (OVP) circuit is presented for use with the AAT123I, an inductive boast con. stant current wtute LED driver.. The circuit allows transition from constant current to constant voilage at the. OVP threshold, maintaining the programmed output voltage and current during
  • Society for Information Display New Products March 2002
