CL88031 230VAC offline LED driver evaluation board. The CL88031 driver Integrated Circuit (IC) is a sequential linear LED driver, 6-tap version, targeted to provide a flexible solution to drive LEDs from AC line voltages up to 277VAC and at high output powers. A sequential linear LED driver is an LED driver, operating from an AC voltage source and comprised of multiple linear current regulators driving various tap points along a long string of LEDs connected to the rectified AC.

• Scalable (AC line voltage limited by external FETs, output power limited by external FETs)
• No inductors (reduces BOM cost and circuit complexity)
• Efficient operation (typical electrical efficiencies of 80 to 90% across AC I/P voltage range)
• No high frequencies (Inherently low-conducted EMI no need for input filters)
• Inherently dimmer compatible
• Overtemperature protection (OTP) optional
• Reduced output ripple (optional)
• Active line regulation
• Two current-setting resistors
