The MAX16840 from Maxim is an LED driver IC for lighting applications and includes all the necessary features to design low-component-count LED drivers for 12 V and 24 V a.c. input light bulbs (eg, MR16). 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) or leading-edge dimmers (where magnetic transformers are present).
The IC can be used in buck, boost and buck-boost topologies. It has an integrated 0,2 Ω, 48 V switching MOSFET that allows for output power levels up to 10 W. The device 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 (REFI) allows the 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, whereas when that voltage is beyond the threshold, the input current is set at a fixed, predefined level. This nonlinear behaviour of REFI allows its use to achieve thermal foldback, by connecting it to an NTC resistor.
