DESCRIPTION
Enable input (active high)
Drive EN high to turn on the MSL2100, and drive it low to turn it off.
For automatic startup, connect EN to VIN through a 100k? resistor.
No internal connection. Recommended to leave open.
Connect to ground
Connect CGND to system ground, to GND, and to EP using short, wide traces.
Phase synchronization input
Drive PHI with an external signal from 40Hz to 10kHz to synchronize the PWM dimming to the signal at PHI.
Connect PHI to GND if unused.
Gate shift clock input
Drive GSC with the gate shift clock of the video signal, up to 5MHz. GSC sets the resolution of PWM dimming.
Connect GSC to GND if unused.
PWM input
Drive PWM with a pulse-width-modulated signal with a duty cycle of 0% to 100% and frequency of 20Hz to 50kHz
to control the brightness of all LED strings.
Power ground
Connect EP to system ground, GND, and CGND using short, wide traces.
EP offers thermal relief to the die.
