The PT6913B-TP with LED Drivers SOT-89-3 RoHS is a 3-channel constant current LED driver IC designed and manufactured by Princeton Technology Corporation. It is a versatile LED driver that features low voltage operation, low power consumption, and high efficiency LED drive. The PT6913B-TP is available in a SOT-89-3 RoHS (Lead-Free) package, which is RoHS compliant and suitable for high reliability applications. This device provides a constant current output with the 3 separate channels allowing users to control each LED brightness independently. It supports operating voltages from 4.5V to 15V, making it suitable for a wide range of applications. Additionally, this device is able to extend existing systems as it is compatible with PWM dimming and analog dimming functions. The PT6913B-TP also supports series and parallel connection which can be used to achieve higher brightness output.
