Product Overview
The MAX31840ATA+ is a MR16 LED driver with integrated control MOSFET and deep dimming in 8 pin TDFN-EP package. It is an LED driver IC for dimmable 12V MR16 as well as AR111 and other 12V lighting applications. It minimizes BOM count, cost and board space by integrating a number of value added functions such as deep dimming, bleeder control, constant brightness control and boost FET while significantly improving electronic transformer compatibility with standard trailing edge dimmers. It is a high end MR16 LED driver that incorporates a proprietary circuit that enables deep dimming down to 1%, an improvement over others that only dim down to 10% or 20%. An integrated bleeder and constant brightness controller enables MAX31840 to shine, flicker free with a broad range of electronic transformers. An optimized compensation circuit and boost FET are integrated to further reduce BOM and board space, simplifying design and saving cost.
- High integration saves PCB space and BOM costs
- 36V boost N-channel DMOS FET, bleeder FET control, flickering
30%, 0.9 power factor - Deep dimming control, constant brightness control, internal compensation
- LED overvoltage protection, overcurrent and overtemperature protection
- High performance for new LED dimming requirements
- 700KHz switching frequency, meets California title 24 part 6 JA8
- Designed for boost architecture to address 35W and higher wattage MR16 LED replacement bulbs
- Tight LED current regulation of 2% typical and dimming to less than 1% brightness depending on LEDs
- 6.5V to 26V operating voltage range, 1mA IN supply current (when MOSFET fully on, VCS = 0)
- Operating temperature range from -40°C to +125°C
- 12V MR16 GU5.3 LED Bulb; Other 12V LED bulbs (MR11, AR111, 12V Track Lighting)
