MAX16840ATB+T - Maxim Integrated Function Overview

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.
Supply voltage range is 6.5V to 48V
Operating temperature range from -40°C to 125°C
Buck, boost, SEPIC and buck-boost topologies
Analogue dimming
Internal overtemperature protection
