Diodes Incorporated's AL1676 universal AC input LED driver is designed to meet or exceed the power factor regulations worldwide for non-dimmable retrofit LED bulbs and tube lighting, providing high efficiency and low bill of materials (BOM) Cost design. Multiple options for integrated MOSFETs allow for drain voltages from 300V to 650V and drain currents from 1A to 4A to suit most 3W to 18W bulbs.
The AL1676 uses a single-stage buck converter topology with constant on-time control for high power factor operation; a simple closed-loop algorithm ensures accurate constant LED output current for good linearity and load regulation. The critical conduction mode simplifies EMI/EMC design requirements while detecting turn-off times, helping to eliminate auxiliary windings and helping the device achieve extremely low BOM counts and costs.
The AL1676 device offers a variety of protection features such as undervoltage and overvoltage, thermal shutdown, and thermal fold-back to increase system reliability when LED bulbs experience high ambient temperatures. The high level of integration combined with the small 5mm x 6mm SO-7 package also enables a very compact solution size; by using different MOSFET options, the same PCB pin design can be reused for different power bulbs.
