The integration of these functions enables saving of external parts and optimizes performance by harmonized operation of the two stages. XDPL8220 uses a constant on-time scheme with a THD improvement algorithm to provide a high power factor and excellent THD performance. With its unique control scheme of CV, CC and LP, the LED driver designer is provided with a large degree of flexibility and can utilize the system hardware to its limits. The on-chip One Time Programmable Memory (OTP) memory has an area for parameters that control the behavior of the circuit, e. g. the output current or the maximum output power. This enables the user of the device to create a platform concept with significantly fewer different hardware versions while still covering the same application range. The two-stage approach reduces any variation in the output current (flicker) to a non-visible level. By separating the PFC from the power conversion part (FB), both stages operate in a more stable manner and require fewer margins, which has a positive influence on the cost. Lighting requires more and more 24/7 operation, making it necessary to have a stand-by mode with short wake- up times and low power consumption. The power consumption of less than 100 mW of the XDPL8220-based systems defines the new standard for stand-by power in lighting ECGs. XDPL8220 enables adaptive temperature protection using either the internal sensor or an external Negative Temperature Coefficient Thermistor (NTC), or both. Futureproof flexibility with application-oriented programmable operating windows enables management of LED generations and portfolio complexity . Data Sheet 2 Revision 1.0 2016-11-4
