Product Description

With PrecisionDrive™ technology, MBI5024 is designed for LED displays which require to operate at low current

and to match the luminous intensity of each channel. It provides supply voltage and accepts CMOS logic input at

3.3V and 5.0V to meet the trend of low power consumption. MBI5024 contains a serial buffer and data latches

which convert serial input data into parallel output format. At MBI5024 output stage, sixteen regulated current ports

are designed to provide uniform and constant current sinks for driving LEDs within a large range of V_Fvariations.

MBI5024 provides users with great flexibility and device performance while using MBI5024 in their system design

for LED display applications, e.g. LED panels. It accepts an input voltage range from 3V to 5.5V and maintains a

constant current up from 3mA to 45mA determined by an external resistor, R_ext, which gives users flexibility in

controlling the light intensity of LEDs. MBI5024 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.

* Among output channels exist 15ns delay time between odd number OUT2n + 1 (e.g.:Bit1/Bit3/Bit5…)and even

which the even and odd output ports will be turned on at a different time so that the instant current from the power

line will be lowered.

Application Information

Constant Current

To design LED displays, MBI5024 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 ±2.5%, and that between ICs is less than ±3%.

2) In addition, the current characteristic of output stage is flat and users can refer to the figure as shown below. The

output current can be kept constant regardless of the variations of LED forward voltages (V_F). This performs as

a perfection of load regulation.

Adjusting Output Current

The output current of each channel (I_OUT) is set by an external resistor, R_ext. The relationship between I_OUTand R_ext

is shown in the following figure.

Also, the output current can be calculated from the equation:

V_R-EXT=1.24V；I_OUT=V_R-EXT*(1/Rext)x15; R_ext=(V_R-EXT/I_OUT)x15

Where R_extis the resistance of the external resistor connected to R-EXT terminal and V_R-EXTis the voltage of R-EXT

Soldering Process of “Pb-free & Green” Package*

Macroblock has defined "Pb-Free & Green" to mean semiconductor products that are compatible with the current

RoHS requirements and selected 100% pure tin (Sn) to provide forward and backward compatibility with both the

current industry-standard SnPb-based soldering processes and higher-temperature Pb-free processes. Pure tin is

widely accepted by customers and suppliers of electronic devices in Europe, Asia and the US as the lead-free

surface finish of choice to replace tin-lead. Also, it is backward compatible to standard 215ºC to 240ºC reflow

processes which adopt tin/lead (SnPb) solder paste. However, in the whole Pb-free soldering processes and

materials, 100% pure tin (Sn), will all require up to 260^oC for proper soldering on boards, referring to J-STD-020C

as shown below.

Package Power Dissipation (PD)

The maximum allowable package power dissipation is determined as P_D(max)=(Tj–Ta)/R_th(j-a). When 16 output

channels are turned on simultaneously, the actual package power dissipation is

P_D(act)=(I_DDxV_DD)+(I_OUTxDutyxV_DSx16). Therefore, to keep P_D(act)≤P_D(max), the allowable maximum output current

as a function of duty cycle is:

I_OUT={[(Tj–Ta)/R_th(j-a)]–(I_DDxV_DD)}/V_DS/Duty/16, where Tj=150°C.

Load Supply Voltage (V_LED)

MBI5024 are designed to operate with V_DSranging from 0.4V to 0.8V (depending on I_OUT=3~45mA) considering the

package power dissipating limits. V_DSmay be higher enough to make P_D(act)>P_D(max)when V_LED=5V and

V_DS=V_LED–V_F, in which V_LEDis the load supply voltage. In this case, it is recommended to use the lowest possible

supply voltage or to set an external voltage reducer, V_DROP

A voltage reducer lets V_DS=(V_LED–V_F)–V_DROP

Switching Noise Reduction

LED driver ICs are frequently used in switch-mode applications which always behave with switching noise due to

the parasitic inductance on PCB. To eliminate switching noise, refer to “Application Note for 8-bit and 16-bit LED

Drivers- Overshoot”.
