Maxim’s MAX31840 is a high-performance LED driver for MR16 and other 12 V LED bulbs that enables designers to meet new LED dimming requirements while also reducing cost, board space, and BOM count. This is possible because the MAX31840 integrates a 36V boost FET, constant brightness control, bleeder control, and proprietary circuitry that enables deep dimming down to approximately 1%, which is a significant improvement over the 10-20% of competing devices. The driver is designed for use in boost architectures 35 W or higher. The MAX31840 uses an input-current control scheme for power factor correction and a 700 kHz switching frequency to minimize flicker and has a tight LED current regulation of 2%.
