MAX16840
EVALUATION KIT AVAILABLE
LED Driver with Integrated MOSFET for MR16 and Other 12V AC Input Lamps
General Description
The MAX16840 is an LED driver IC for lighting applications. It includes all the necessary features to design lowcomponent-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).
The IC can be used in buck, boost, and buck-boost topologies and features. It has an integrated 0.2I (max), 48V switching MOSFET.
The IC uses constant-frequency average current-mode control.
