CL520K4-G

Supertex inc. CL520 Linear, Fixed Constant Current LED Driver General Description Features The CL520 is a fixed, linear current regulator designed for driving LEDs at 20mA. With a maximum rating of 90V, it is able to withstand transients without the need for additional transient protection circuitry. It is ideally suited for applications employing single or multiple LEDs. ►► 20mA ±10% constant current drive ►► 1.0V dropout ►► 90V rating for transient immunity ►► Temperature compensated ►► 4.75 - 90V supply range The minimum dropout voltage of 1.0V accomodates extra LEDs, permits lower supply voltages, and provides more efficient operation. Applications ►► Specialty lighting ►► Low voltage signage The CL520 is offered in TO-252(D-PAK) and TO-92 packages.
