O2Micro, a supplier of industry-leading product line of power management and e-commerce ICs, has launched OZ8022M high brightness offline LED driver controller which provides three-step dimming using any ordinary non-dimming on/off switch.
 
The OZ8022M dims from 100% to 40% to 2.5%, a low level night light mode. Consumers gain a built-in, free night-light while OEMs gain a value-added feature in a market sorely lacking in differentiation.
 
The OZ8022M supports universal 85V to 265V operation, enabling one LED bulb to address the global marketplace. High efficiency greater than 89% reduces energy consumption and thermal management complexity. Integrated over-temperature, over-voltage, cycle-by-cycle current limiting, and LED short circuit protection provides safe and reliable operation. Excellent LED current regulation ensures consistent lumen output, regardless of varying line input conditions.
 
The OZ8022M is available in a SOT-23-6 package and is pin compatible with the OZ8022A and OZ8022B. The OZ8022M is in high volume production now. Samples and evaluation boards are available now for qualified customers.
