.
B1
SYNC
Analog Input
Synchronization input for the PWM converter. If a clock signal is present, the converter
uses the rising edge for the turn on. If this pin is low, the converter is in the Pulsed mode.
If this pin is high, the converter uses the internal oscillator for the PWM mode. This pin
contains an internal pull down resistor.
B2
GNDA
Analog Ground
Ground connection for the Analog Section of the IC. This is the GND for the FB, Ref,
Sync, CB, and SHD pins.
B3
FB
Analog Input
Feedback Voltage from the Output of the Power Supply.
C1
SHD
Analog Input
Enable for Switching Regulator. This Pin is Active High to enable the NCP1511. The SHD
Pin has an internal pull down resistor to force the converter off if this pin is not connected
to the external circuit.
C2
CB1
Analog Input
Selects V

. This pin contains an internal pull up resistor.
C3
CB0
Analog Input
Selects V
out
. This pin contains an internal pull down resistor.
