PIN DESCRIPTIONS Pin Number Name Description 1 VIN Power supply input. Connect to the input filter capacitor ( Figure 1). 2 GND Ground pin. Enable input. The device is in shutdown mode when voltage to this pin is <0.4V and enable when 3 EN >1.0V. Do not leave this pin floating. Feedback analog input. Connect to the output filter capacitor for fixed voltage versions. For adjustable 4 FB version external resistor dividers are required ( Figure 2). The internal resistor dividers are disabled for the adjustable version. 5 SW Switching node connection to the internal PFET switch and NFET synchronous rectifier. 2 Submit Documentation Feedback Copyright © 2005–2013, Texas Instruments Incorporated Product Folder Links: LM3674 |
