DESCRIPTION
Drain sense input 13
Drain sense input for external MOSFET 13.
Connect D13 through a 10MΩ resistor to the drain of the external MOSFET driving LED string 13.
Current sense input 14
Current sense input for LED string 14.
Connect S14 to the source of the external MOSFET and to the current sense resistor for LED string 14.
The full-scale LED current threshold is 500mV is across the current sense resistor.
Gate output 14
Gate drive output for external MOSFET 14.
Connect G14 to the gate of the external MOSFET driving LED string 14.

Current sense input 15
Current sense input for LED string 15.
Connect S15 to the source of the external MOSFET and to the current sense resistor for LED string 15.
The full-scale LED current threshold is 500mV is across the current sense resistor.
Gate output 15
Gate drive output for external MOSFET 15.
Connect G15 to the gate of the external MOSFET driving LED string 15.
Drain Sense Input 15
Drain sense input for external MOSFET 15.
Connect D15 through a 10MΩ resistor to the drain of the external MOSFET driving LED string 15.
5V internal LDO regulator output
VCC powers the FBO outputs.
Bypass VCC to ground with a 4.7μF ceramic capacitor placed close to VCC.
Phase synchronization input
Drive PHI with an external signal from 40Hz to 10khz
kHz to synchronize the MSL2162 clock. In TV applications drive PHI with the VSYNC signal.
Gate shift clock input
Drive GSC with the gate shift clock of the video signal, from 0 to 10khz
MHz. In TV applications drive GSC with the HSYNC signal.
PWM input
PWM allows external control of the brightness of all LED strings.
Drive PWM with a pulse-width modulated signal with duty ratio ranging from 0% to 100% and frequency up
to 5kHz. When not configured as an input, PWM is high impedance.
