IRS2166CD is a ballast controller PMIC that is designed for use in industrial, architectural, and decorative lighting. The device integrates all of the necessary functional blocks required for a complete ballast solution, including a high accuracy PWM dimmer, EMI filtration, overvoltage protection, and an integrated EMI filter. It also features a range of low dropout (LDO) regulators, enabling the device to support up to six different output voltages, as well as an integrated 120V/220V AC mains switch and a programmable timer. The IRS2166CD is certified to UL, UL14E, and ENEC standards, making it suitable for high power applications.The device provides a high-accuracy, programmable pulse-width modulation (PWM) dimming capability, with a switching frequency of up to 100kHz, to enable high power savings in lighting applications. It also has a MOSFET shutdown circuit with an adjustable dead-time delay, allowing for additional power savings in energy-saving lighting systems. The integrated EMI filter eliminates line noise interference and reduces the radiated emission from lighting systems.The device integrates a programmable timer, which can be programmed to delay the turn-on of a light source, and a wide-range of low dropout (LDO) regulators, with output voltages of 5V, 6V, 9V, 10V, 12V, and 16V. This provides additional flexibility for supporting various lighting applications. The device also features an integrated 120V/220V AC mains switch, allowing the device to be used in 120V or 220V systems.In addition to the power and control features, the device also has several safety features such as reverse polarity protection and overvoltage protection. The device is also capable of monitoring current and power consumption, and has a thermal shutdown circuitry to prevent overheating.Overall, the IRS2166CD is a highly integrated PMIC solution for the ballast market. It provides an efficient, cost effective solution for low power lighting applications, and is suitable for applications in both residential and commercial buildings.
