Pin configuration Pin No. Symbol I/O Description This is the ON/OFF control pin of the device. Connecting this pin to GND keeps the device in shutdown mode. 7 EN Input Pulling this pin to Vin enables the device with soft start. This pin must not be left floating and must be terminated. EN=H: Device ON, EN=L: Device OFF Regulated voltage output pin. 2,3 Vout Output Apply output load between this pin and GND. 4,8,9 GND - Ground pin 5,6 Vin Input Vin pin supplies current to the LXDC2XQ internal regulator This is the operation mode select pin. This pin must not be left floating and must be terminated. Mode=H: Low-noise mode enabled, frequency PWM operation is forced. 1 MODE Input Mode=L: This device is operating in pulse frequency modulation mode (PFM) at light load currents, and in regulated frequency pulse width mode (PWM) at high-load currents. 2 July. 2015
