MR16 LED Driver with Integrated Control

MOSFET and Deep Dimming

General Description

Beneﬁts and Features

● High Integration Saves PCB Space and BOM Costs

• 36V Boost N-Channel DMOS FET

• Bleeder FET Control

The MAX31840 is an LED driver IC for dimmable 12V

MR16,aswellasAR111andother12Vlightingapplications.

This next-generation MR16 LED driver minimizes BOM

count, cost, and board space by integrating a number of

value-added functions: deep dimming, bleeder control,

constant brightness control, and a boost FET; while

significantly improving electronic transformer compatibility

with standard trailing-edge dimmers. The MAX31840 is

designed for the boost architecture to address 35W and

higher-wattage MR16 LED replacement bulbs.

• Deep Dimming Control

• Constant Brightness Control

• Internal Compensation

• LED Overvoltage Protection

• Overcurrent and Overtemperature Protection

● High-Performance for New LED Dimming

Requirements

• Meets California Title 24 Part 6 JA8

• Flickering < 30%

• > 0.9 Power Factor

• Dimming to <1% Brightness, Depending on LEDs

• Tight LED Current Regulation of 2% Typical

The MAX31840 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 the 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.

Ordering Information appears at end of data sheet.

The MAX31840 is available in an 8-pin, 3mm x 3mm

TDFN enhanced power package and is rated over the

-40°C to +125°C operating temperature range.

Applications

● 12V MR16 GU5.3 LED Bulb

● Other 12V LED bulbs (MR11, AR111, 12V Track Lighting)
