PT16977

PT16977 is a three-channel linear constant current LED driver with analog and PWM dimming control, and each channel has independent PWM dimming. The driver designed to accommodate a slow input voltage of 0.5 V/min with no issues. Its full-diagnostic and built-in protection capabilities make it a suitable choice for variable-intensity LED lighting applications up to the medium-power range. 

The device is available in a HTSSOP16 package, and the operating junction temperature range is –40°C to 150°C.
