VOUT A1 O Power output pin. Apply output load between this pin and GND. VIN A2, A3 I The VIN pins supply current to the TPS8269xSIP's internal regulator. This is the enable pin of the device. Connecting this pin to ground forces the converter into EN B2 I shutdown mode. Pulling this pin to VIN enables the device. This pin must not be left floating and must be terminated. This is the mode selection pin of the device. This pin must not be left floating and must be terminated. MODE = LOW: The device is operating in regulated frequency pulse width modulation mode MODE B1 I (PWM) at high-load currents and in pulse frequency modulation mode (PFM) at light load currents. MODE = HIGH: Low-noise mode enabled, regulated frequency PWM operation forced. GND C1, C2, C3 – Ground pin.
