The MAX16840ATB+T is an LED driver integrated circuit from Analog Devices, suitable for low-component-count LED drivers for 12V AC and 24V AC input applications, such as MR16 light bulbs. It utilizes a proprietary input-current control scheme for compatibility with electronic transformers and dimmability with standard trailing-edge dimmers.
This IC supports buck, boost, and buck-boost topologies and includes an integrated 0.2Ω (max), 48V switching MOSFET. It operates using constant-frequency average current-mode control and features an input pin (REFI) for setting input-current levels, which can also be used for thermal foldback protection when connected to an NTC resistor. The device includes internal overvoltage protection on the IN pin and an EXT pin for kick-start current at turn-on for low-input voltages.
The MAX16840ATB+T is available in a 10-pin TDFN (3x3mm) power package. It operates over a wide temperature range of -40°C to +125°C, enhancing reliability. The device is designed for cost-effectiveness and minimal component count, saving space and cost in SSL applications.
Key electrical specifications include an input voltage range starting at 6.5V, an output voltage capability up to 48V, a current rating of 800mA, and a switching frequency of 300kHz. It supports analog dimming and is housed in a 10-WFDFN exposed pad package suitable for surface mounting.
