FB C1 I Output feedback sense input. Connect FB to the converter’s output. VIN A2 I Power supply input. SW B1 I/O This is the switch pin of the converter and is connected to the drain of the internal Power MOSFETs. This is the enable pin of the device. Connecting this pin to ground forces the device into shutdown mode. EN B2 I Pulling this pin to VI enables the device. If an external clock (4MHz to 27MHz) is detected the device will automatically power up. 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 (PWM) at high- MODE A1 I 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 C2 – Ground pin. 4 Submit Documentation Feedback Copyright © 2010–2014, Texas Instruments Incorporated Product Folder Links: TPS62671 TPS62672 TPS62674 TPS62675 TPS626751 TPS626765 TPS62679 |
