3 / 21 page Pin Functions V SW(Pin 1): This is the drain of the internal NMOS power switch. Minimize the metal trace area connected to this pin to minimize EMI. V IN(Pin 2): Input Supply Pin. Bypass this pin with a capacitor as close to the device as possible. The capacitor should connect between V IN and GND. SHDN(Pin 3): Shutdown Pin. The shutdown pin signal is active low. A voltage of less than 0.3V disables the device. A voltage greater than 0.85V enables the device. FSLCT(Pin 4): Frequency Select Pin. Connecting FSLCT to AGND selects a 600 kHz operating frequency for the switch- ing regulator. Connecting FSLCT to V IN selects a 1.25 MHz operating frequency. If FSLCT is left floating, the switching frequency defaults to 600 kHz. Vs+(Pin 5): Supply pin for the four Gamma buffers. Bypass this pin with a capacitor as close to the device as possible. The capacitor should connect between Vs+ and GND. GMA1-in(Pin 6):Gamma Buffer input pin. GMA2-in(Pin 7): Gamma Buffer input pin. GMA3-in(Pin 8): Gamma Buffer input pin. GMA4-in(Pin 9): Gamma Buffer input pin. NC(Pin 10):No Connection. NC(Pin 11): No Connection. GMA4-out(Pin 12): Gamma Buffer output pin. GMA3-out(Pin13): Gamma Buffer output pin. GMA2-out(Pin 14): Gamma Buffer output pin. GMA1-out(Pin 15): Gamma Buffer output pin. SS(Pin 16): Softstart pin. Connect capacitor to SS pin and AGND to slowly ramp inductor current on startup. V C(Pin 17): Compensation Network for Boost switching regulator. Connect resistor/capacitor network between V C pin and AGND for boost switching regulator AC compensa- tion. FB(Pin 18): Feedback pin. Set the output voltage by select- ing values of R1 and R2 using: Connect the ground of the feedback network to the AGND plane, which can be tied directly to the GND pin. AGND(Pin 19): Analog ground pin. Ground connection for the Gamma buffers and the boost switching regulator. AGND must be tied directly to GND at the pins. GND(Pin 20): Power ground pin. Ground connection for the NMOS power device of the boost switching regulator. GND must be tied directly to AGND at the pins.
