tm TE CH T8611 High Voltage Constant-Current Driver FEATURES GENERAL DESCRIPTION • Wide operating voltage range : 5V to 90V • Output current tolerance: ±10% • Connected in parallel for higher current • RoHS and green compliant packages: SOT-89 and SOT-23 The T8611 is a simple, high voltage, linear current regulator. It drives LEDs at 15mA~25mA(±10%) at an input voltage of 5V~90Vdc. The T8611 can be used as a constant current source or a constant current sink. Multiple T8611 can be connected in parallel to supply higher constant currents, such as double or higher current. For wider application, the T8611 is available in SOT-89 and SOT-23. APPLICATIONS • LED Driver • LED traffic light • Constant current source or current sink • Signage • Decorative LED lamp TM Technology, Inc. reserves the right to change products or specifications without notice.
