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 TPS8267x internal regulator. This is the enable pin of the device. Connect this pin to ground to force the converter into EN B2 I shutdown mode. Pull this pin to VI to enable 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 is enabled and regulated frequency PWM operation is forced. GND C1, C2, C3 – Ground pin. 4 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s): TPS82671 TPS82675 |
