Microchip CL320SG-G

线性6.5V90V20mA

Overview

The CL320SG-G is designed to drive 3 strings of LEDs at a constant current of 20mA. Other drivers with currents in the range of 20 - 30mA are available. The drive current is fixed, with a ±6% tolerance over a VOUT range of 4.0 - 15V. Separate enable pins for each channel allow for PWM dimming, 3-step linear dimming, or individual disconnection of faulty LED strings. Over-temperature protection circuitry shuts down all 3 channels when the nominal die temperature reaches 135°C. Normal operation resumes when the die temperature drops by 30°C.The CL320SG-G is available in the 8-Lead SOIC (w/Heat Slug) package and requires a single ceramic bypass capacitor which may be shared among several drivers.
