Efficiency optimizer feedback output 1
Connect FBO1 to the feedback node of the first external string power supply through a diode,
or to FBI1 of the next device when operating the devices in a chain configuration.
If unused, leave FBO1 unconnected.
Enable input (Active high)
Drive EN high to turn on the MSL2041/2, drive it low to turn off the MSL2041/2. For automatic
startup connect EN to VIN through a 100kΩ resistor. Toggle EN low to release FLTB and to
return any and all registers to their power-up default values.
PWM dimming input 3
Drive PWM3 with a pulse-width modulated signal to control the brightness of string three.
If unused, connect PWM3 to ground.
PWM dimming input 2
Drive PWM2 with a pulse-width modulated signal to control the brightness of string two.
If unused, connect PWM2 to ground.
PWM dimming input 1
Drive PWM1 with a pulse-width modulated signal to control the brightness of string one.
If unused, connect PWM1 to ground.
Pwm dimming input 0
Drive PWM0 with a pulse-width modulated signal to control the brightness of string zero
(MSL2041) or all strings (MSL2042).
Fault indication output (Open drain, active low)
FLTB sinks current to GND whenever the MSL2041/2 detects and verifies a fault condition.
Toggle EN low (or read the fault registers) to clear FLTB.
I2C serial clock input
SCL is the I2C serial interface clock input.
I2C serial data I/O
SDA is the I2C serial interface bi-directional data line.
Drain sense input 0
Drain Sense Input for External MOSFET 0. Connect D0 through a resistor to the drain of the
external MOSFET driving LED string 0. If unused, connect D0 to ground.
Gate output 0
Gate drive output for external MOSFET 0. Connect G0 to the gate of the external MOSFET
driving LED string 0. If unused, connect G0 to ground.
Source sense input for string 0
Connect S0 to the source of the external MOSFET, and to the current sense resistor for
LED string 0. The full scale LED current is reached when 500mV is across the current sense
resistor. If unused, connect S0 to VDD.
Drain sense input 1
Drain Sense Input for External MOSFET 1. Connect D1 through a resistor to the drain of the
external MOSFET driving LED string 1. If unused, connect D1 to ground.
Gate output 1
Gate drive output for external MOSFET 1. Connect G1 to the gate of the external MOSFET
driving LED string 1. If unused, connect G1 to ground.
Source sense input for string 1
Connect S1 to the source of the external MOSFET, and to the current sense resistor for
LED string 1. The full scale LED current is reached when 500mV is across the current sense
resistor. If unused, connect S1 to VDD
No internal connection
NC is not internally connected .
Drain sense input 2
Drain Sense Input for External MOSFET 2. Connect D2 through a resistor to the drain of the
external MOSFET driving LED string 2. If unused, connect D2 to ground.
