Product Description
MBI5035 is a 16-channel constant current LED driver with VDS=0.2V @ IOUT=20mA, which is excellent compared to
the conventional design. MBI5035 is especially designed for low power consumption LED display applications. The
low knee voltage (LKV) design makes MBI5035 work at a constant output current with low VDS and still guarantees
PrecisionDrive™ feature. With PrecisionDrive™, MBI5035 is designed for LED displays which require to operate at
low current and match the luminous intensity of each channel. MBI5035 contains a serial buffer and data latches
which convert serial input data into parallel output format. At MBI5035 output stage, sixteen regulated current ports
are designed to provide uniform and constant current sinks for driving LEDs within a large range of VF variations.
MBI5035 provides users with great flexibility and device performance in their low power system design for LED
display applications. It accepts an input voltage range from 3.3V to 5.0V and maintains constant current up from
3mA to 40mA determined by an external resistor, Rext, which gives users flexibility in controlling the light intensity of
LEDs. MBI5035 guarantees to endure maximum 17V at the output port. The high clock frequency, 25 MHz, also
satisfies the system requirements of high volume data transmission.

*The PCB size is 76.2mm*114.3mm in simulation. Please refer to JEDEC JESD51.
Note: The performance of thermal dissipation is strongly related to the size of thermal pad, thickness and layer
numbers of the PCB. The empirical thermal resistance may be different from simulative value. User should plan for
expected thermal dissipation performance by selecting package and arranging layout of the PCB to maximize the
capability.
** Operation at the maximum rating for extended periods may reduce the device reliability; therefore, the suggested
operation temperature of the device is under 125°C.

Application Information
16-Channel Constant Current LED Driver
with Low Knee Voltage
Constant Current
To design LED displays, MBI5035 provides nearly no variations in current from channel to channel and from IC to IC.
This can be achieved by:
1) The maximum current variation between channels is less than ±3%, and that between ICs is less than ±6%.
2) In addition, the current characteristic of output stage is flat and users can refer to the below figure. The output
current can be kept constant regardless of the variations of LED forward voltages(VF). This performs as a perfect
static load regulation.
