Maxim's high-brightness LED (HB LED) drivers are dedicated integrated circuits for driving white or RGB LEDs. They are energy-saving, cost-effective choices that enable the next generation of projection, automotive, and general lighting applications.
The MAX16840 is an LED driver IC for lighting applications. It includes all the necessary features to design low-component-count LED drivers for 12V AC and 24V AC input (e.g., MR16) light bulbs. A proprietary input-current control scheme allows LED lamps based on this device to be compatible with electronic transformers, and dimmable with standard trailing-edge dimmers (where electronic transformers are present).
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
- 3mm x 3mm, 10-Pin TDFN Package
