QFN 13-Pin VCA Package Table 5-1. Pin Functions PIN TYPE(1) DESCRIPTION NAME SIE VCA EN 2 9 I This 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. FB 7 3 I Voltage feedback input. Connect the output voltage resistor divider to this pin. GND 6, 10, 13, 14 2, 6, 12 Ground pin MODE/ SYNC 4 11 I The device runs in PSM (auto PFM/PWM transition) mode when this pin is pulled low. When the pin is pulled high, the device runs in forced PWM mode. Do not leave this pin unconnected. The MODE/SYNC pin can also be used to synchronize the device to an external frequency. See Synchronizing to an External Clock. COMP/ FSET 9 5 I Device 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. The switching frequency is set to 2.25 MHz if the pin is tied to GND or VIN. Spread spectrum is also enabled and disabled by this pin. See COMP/FSET. Do not leave this pin unconnected.
