Microchip Technology CL52x Linear Fixed Constant Current LED Drivers

Microchip CL52x Linear Fixed Constant Current LED Drivers are fixed, linear current regulators designed for driving LEDs at 20mA or 25mA. With a maximum rating of 90V, they are able to withstand transients without the need for additional transient protection circuitry. Microchip CL52x Linear Fixed Constant Current LED Drivers are ideally suited for applications employing single or multiple LEDs. The minimum dropout voltage of 1.0V accommodates extra LEDs, permits lower supply voltages, and provides more efficient operation.

Features

  • 20mA or 25mA ±10% constant current drive
  • 1.0V dropout
  • 90V rating for transient immunity
  • Temperature-compensated
  • 4.75 - 90V supply range

Applications

  • Specialty lighting
  • Low voltage signage
