Efficiency Optimizer input 2
Connect FBI2 to FBO2 of the next device when chaining devices (Figure 7). If unused connect FBI2 to GND.
Efficiency Optimizer output 3
Connect FBO3 to the third power supply’s feedback node or to FBI3 of the previous device when chaining
devices (Figure 7). If unused connect FBO3 to GND.
Efficiency Optimizer input 3
Connect FBI3 to FBO3 of the next device when chaining devices (Figure 7). If unused connect FBI3 to GND.
Phase synchronization input
Drive PHI with an external signal from 40Hz to 10kHz to synchronize the MSL3163/4 clock. PHI is typically
the VSYNC signal input.
Gate shift clock input
Drive GSC with the gate shift clock of the video signal, from 0 to 10MHz.
GSC is typically the HSYNC signal input.
PWM input
PWM allows direct external control of the brightness of all LED strings. The PWM input may also be
used as a gate signal for the output of the PWM. Drive PWM with a pulse-width modulated signal with
duty ratio ranging from 0% to 100% and frequency up to 5kHz.When not configured for use as an input
PWM is high-impedance.
LED string current sink outputs
Connect the cathode of the n’th strings bottom LEDs to STRn. Connect unused STRn outputs to GND.
Connect to ground
Connect CGND to GND and to EP with short, wide traces.
Signal ground
Connect all GNDs to system ground and to EP with short, wide traces.
Fault indication output (active low)
Open drain output FLTB sinks current to GND whenever a fault condition is verified. Toggle EN low or read
the fault registers to clear FLTB. Once cleared, FLTB reasserts if the fault conditions persist.
AD0, AD1 AD0, AD1 Slave ID AD1 and AD0 to GND through resistors to set the device address for the serial interface.

MSL3163: I2C serial clock input
SCL is the clock input for the I2C serial interface.
MSL3164: SPI serial shift clock
SCK is the clock input for the SPI interface.
MSL3163: factory test I/O
Factory test. Make no electrical connection to TEST.
MSL3164: Master input slave output
MISO is the SPI serial data output.
MSL3163: I2C serial data I/O
SDA is the data I/O for the I2C serial interface.
MSL3164: Master input slave output
MOSI is the SPI serial data input.
MSL3163: ground.
Connect GND to system ground and to EP with short, wide traces.
MSL3164: chip select (active low)
CSB is the chip select input for SPI transactions. CSB is active low.
Maximum LED string current setting input
Connect a resistor from ILED to GND to set the full-scale LED string current for all strings using
I STRING = 762 / R ILED . For example, connect a 12.7k? resistor to GND to set a 60mA maximum sink current
through each LED string.
Enable input (Active high)
Drive EN high to turn on the MSL3163/4, drive EN low to turn off the MSL3163/4. For automatic startup
connect EN to VIN. When EN is low the entire device, including the serial interface, is turned off. Driving EN
high initiates a boot load of the E 2 PROM data into the control registers, simulating a cold start-up.
Supply voltage input
Connect a 5V supply to VIN. Bypass VIN to GND with a 10μF ceramic capacitor placed close to VIN.
