Product Brief ICL8201 AC/DC Buck Controller with high Power Factor for LED Tubes The ICL8201 is a cascode structure current mode controller for non-isolated floating buck topologies. The cascode topology enables lower system cost and higher system efficiency. Key Features Cascode topology enables lower Lower system cost: No auxiliary winding is required to power the IC No high voltage start up depletion Mosfet is required, fast time to light can be achieved inherently with cascode topology Higher system efficiency & reliability: No start up resistor is required that would cause significant losses during the entire operation. These losses can be eliminated by using the cascode topology which increases the system efficiency and lifetime. ICL8201 can provide up to 500mA output current that can cover the entire power range for LED tubes. The device is tailored for LED tube applications and provides constant current operation with low output ripple in a real universal input voltage range as well as load compensation for a wide output voltage range. The high level of integration enables a minimum of effort for addition of external components. The control concept of the IC supports DC and AC input as well as high Power Factor Correction (PFC), high efficiency levels and reduced EMI design in Critical Conduction operation Mode without zero crossing detection winding. Integrated Over-Temperature Protection supports high reliability and long lifetime of the LED lamps. An external NTC is not required which helps to reduce the system cost. The SOT23-6 package supports small form factors and low-cost designs.
