LED drivers deliver 1,0 V dropout

4 February 2009 Opto-Electronics

Supertex has introduced the CL520 and the CL525, two linear, constant current, two-terminal LED drivers with only 1,0 V dropout and fixed output currents of 20 mA and 25 mA, respectively.

The devices are ideally suited for general lighting applications employing single or multiple LEDs, such as decorative lighting and low-voltage signage or channel lighting.

Both ICs feature temperature compensated output currents to maintain consistent LED brightness regardless of temperature. With maximum ratings of 90 V, they are able to withstand transients without any additional transient protection circuitry when used as recommended.

The devices are available in RoHS-compliant TO-92 and D-PAK packages.
