PIN DESCRIPTION
Analog LED current dimming input
Apply a voltage between 0V to 1.22V to linearly control the LED current from 0 to 100%.
Connect IADJ to VDD if unused
LED string 5 current sink output
Connect the cathode of LED String 5 to STR5. Connect STR5 to GND if unused
LED string 4 current sink output
Connect the cathode of LED String 4 to STR4. Connect STR4 to GND if unused
LED string 3 current sink output
Connect the cathode of LED String 3 to STR3. Connect STR3 to GND if unused
LED string 2 current sink output
Connect the cathode of LED String 2 to STR2. Connect STR2 to GND if unused
LED string 1 current sink output
Connect the cathode of LED String 1 to STR1. Connect STR1 to GND if unused
LED string 0 current sink output
Connect the cathode of LED String 0 to STR0. Connect STR0 to GND if unused
Overvoltage detection input
Connect a resistive voltage divider from the boost output voltage to OVP to set the
overvoltage protection set point. OVP threshold is 1.28V
No internal connection. Leave unconnected
Drain of the internal boost power MOSFET switch
Connect all SW pins together and to the boost regulator inductor and rectifier
No internal connection. Leave unconnected
Enable input (active high)
Drive EN high to turn on the MSL1061/64, and drive it low to turn it off.
For automatic startup, connect EN to VIN through a 100k? resistor
Supply voltage input
Connect the input supply voltage to VIN.
VIN powers the internal linear regulator that powers VCC.
Bypass VIN to GND with a 1μF or greater ceramic capacitor
Ground
