PIN DESCRIPTION
Efficiency Optimizer feedback inputs
When using a common LED voltage over multiple MSL3162s, connect FBIs and FBOs in a chain,
with the first FBI grounded and the last FBO controlling the external power source. For standalone
operation, connect FBI to GND.
Efficiency Optimizer feedback outputs
FBO controls the external regulator to dynamically adjust the LED voltage for optimal efficiency.
When using a common LED voltage over multiple MSL3162s, connect FBIs and FBOs in a chain,
with the first FBI grounded and the last FBO driving the feedback node of an external power source.
Signal ground
Connect all CGND and GND pins to system GND and to the exposed pad, EP, using short, wide
traces as close to the MSL3162 as possible
Power ground
Connect all GND and CGND pins to system GND and to the exposed pad, EP, using short, wide
traces as close to the MSL3162 as possible
Phase synchronization input
Drive PHI with an external signal from 40Hz to 10kHz to synchronize the MSL3162 PWM dimming to
the signal at PHI. Connect PHI to GND if unused.
Gate shift clock input
GSC sets the PWM dimming resolution. Drive GSC with the video signal gate shift clock up to 5MHz.
Connect GSC to GND if unused.
PWM dimming input
Drive PWM with a pulse-width modulated signal with a duty ratio ranging from 0% to 100% and
frequency from 20Hz to 50kHz to control the brightness of all LED strings.
STR0 to STR15 LED string current sink outputs
Connect the cathode end of each series LED string to one of STR0 to STR15. Connect unused
outputs to GND, and disable unused strings using the master control registers.
Fault indication output (open drain, active low)
FLTB sinks current to GND whenever the MSL3162 detects a fault. Once a fault is detected, FLTB
remains low until the fault registers have been read.
I2C slave ID selection inputs
AD0 and AD1 select the I2C slave address used. Connect AD0 and AD1 to either GND, VDD, SCL, or
SDA to select the slave ID.
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
Factory connection. Leave unconnected.
Maximum LED current control input
Connect a resistor from ILED to GND to set the full-scale LED string current. A 34.8k? resistor to
GND sets a 60mA sink current through each LED string.
Enable input (active high)
Drive EN high to turn on the MSL3162, and drive it low to turn it off. For automatic start-up, connect
EN to VIN.
