PINI/ODESCRIPTION
NAMENO.
EN8IThis pin is the enable pin of the device. Connect to logic low to disable the device. Pull high to enable the device. Do not leave this pin unconnected.
FB5IVoltage feedback input, connect the resistive output voltage divider to this pin. For the fixed voltage versions, connect the FB pin directly to the output voltage.
GND4Ground pin
MODE/SYNC1IThe device runs in PFM/PWM mode when this pin is pulled low. If the pin is pulled high, the device runs in forced PWM mode. Do not leave this pin unconnected. The mode pin can also be used to synchronize the device to an external frequency. See the Section 7 for the detailed specification of the digital signal applied to this pin for external synchronization.
COMP/FSET7IDevice compensation and frequency set input. A resistor from this pin to GND defines the compensation of the control loop as well as the switching frequency if not externally synchronized. If the pin is tied to GND or VIN, the switching frequency is set to 2.25 MHz. Do not leave this pin unconnected.
PG9OOpen drain power good output. Low impedance when not "power good", high impedance when "power good". This pin can be left open or be tied to GND when not used.
SS/TR6ISoft-Start / Tracking pin. A capacitor connected from this pin to GND defines the rise time for the internal reference voltage. The pin can also be used as an input for tracking and sequencing - see the Soft Start / Tracking (SS/TR) section.
SW3This pin is the switch pin of the converter and is connected to the internal Power MOSFETs.
VIN2Power supply input. Connect the input capacitor as close as possible between pin VIN and GND.
