DESCRIPTION
I2C slave ID selection inputs
AD1 and AD0 select the device I2C slave address.
I2C serial clock input
SCL is the I2C serial interface clock input.
I2C serial data I/O
SDA is the I2C serial interface data I/O.
I2C slave ID selection inputs
AD0 and AD1 select the device I2C slave address.
Fault output (open drain, active low)
FLTB sinks current to GND when the MSL2100 detects a fault.
FLTB remains low until the fault registers have been read or EN is toggled low.
Efficiency Optimizer input
Connect FBI1 to FBO1 of the next device when chaining the Efficiency Optimizers.
If unused, connect FBI1 to GND.
Efficiency Optimizer output
Connect FBO1 through a Schottky diode to the string power supply’s feedback node (Figure 4)
or to FBI1 of the previous device (Figure 5).
If unused, leave FBO1unconnected.
Efficiency Optimizer input
Connect FBI2 to FBO2 of the next device when chaining the efficiency optimizers.
If unused, connect FBI2 to GND.
Efficiency Optimizer output
Connect FBO2 through a Schottky diode to the string power supply’s feedback node (Figure 4)
or to FBI2 of the previous device (Figure 5).
If unused, leave FBO2 unconnected.
Efficiency Optimizer input
Connect FBI3 to FBO3 of the next device when chaining the efficiency optimizers.
If unused connect FBI3 to GND.
Efficiency Optimizer output
Connect FBO3 through a Schottky diode to the string power supply’s feedback node (Figure 4)
or to FBI3 of the previous device (Figure 5).
If unused, leave FBO3 unconnected.
Power ground
Connect GND to system ground, to CGND, and to EP with short, wide traces.
String 0 thru 7 source sense inputs
Connect S n to the source of external MOSFET n and to the current sense resistor for LED string n .
The full-scale LED current is reached when 500mV is across the current sense resistor.
String 0 thru 7 external MOSFET gate drive outputs
Connect G n to the gate of external MOSFET n .
String 0 thru 7 external MOSFET drain sense inputs
Connect D n to the drain of external MOSFET n through a 10M? resistor.
Supply voltage input
Connect a 12V ±10% supply to VIN.
Bypass VIN to GND with a 1μF ceramic capacitor placed close to VIN.
Internal 2.5V regulator capacitor connection
Bypass VDD to GND with a 10μF ceramic capacitor placed close to the device.
