产品概述
The MAX16840ATB+T is a LED driver with integrated MOSFET for MR16 and other 12VAC input lamps in 10 pin TDFN package. It features to design low-component-count LED drivers for 12VAC and 24VAC input light bulbs. An input-current control scheme allows LED lamps based on this device to be compatible with electronic transformers and dimmable with standard trailing-edge dimmers. It has an integrated 0.2ohm (max), 48V switching MOSFET & uses constant-frequency average current-mode control. It senses the input current through the voltage at the FB pin and regulates its average. An input pin allows setting of the input-current level. When the voltage at this pin is set below a certain threshold, the input current is proportional to this voltage, while when that voltage is beyond the threshold, the input current is set at a fixed, predefined level. This non linear behaviour of REFI allows its use to achieve thermal foldback by connecting it to an NTC resistor.
