Maxim Integrated MAX16840 LED Driver with Integrated MOSFET The Maxim Integrated MAX16840 LED driver with integrated MOSFET features a proprietary input-current control scheme allowing LED lamps to be compatible with electronic transformers and dimmable with standard trailing-edge dimmers (where electronic transformers are present). The Maxim Integrated MAX16840 LED driver can be used in buck, boost, and buck-boost topologies. It has an integrated 0.2Ω (max), 48V switching MOSFET and uses constant-frequency average current-mode control. The Maxim Integrated MAX16840 LED driver features analog dimming and thermal foldback and includes output overvoltage protection and internal overtemperature protection. This Maxim Integrated LED driver is designed for use in MR16 and other 12V AC or DC input LED applications. Features Control of the Average Input Current to Achieve Operation with Electronic Transformers and Dimmability Buck, Boost, SEPIC, and Buck-Boost Topologies Integrated 0.2Ω(max) 48V Switching MOSFET Analog Dimming and Thermal Foldback Output Overvoltage Protection Internal Overtemperature Protection -40°C to +125°C Operating Temperature Range 3mmx3mm, 10-Pin TDFN Package Applications MR16 and Other 12V AC or DC Input LED Lighting Applications Block Diagram
