Connect to the input filter capacitor (see Input Capacitor Selection). GND 2 A3 2 Ground Ground pin. EN 3 C1 1 Digital Enable pin. The device is in shutdown mode when voltage to this pin is < 0.4 V and enabled when > 1 V. Do not leave this pin floating. FB 4 C3 6 Analog Feedback analog input. Connect directly to the output filter capacitor for fixed voltage versions. For adjustable version external resistor dividers are required (see Typical Application: ADJ Version). The internal resistor dividers are disabled for the adjustable version. SW 5 B2 4 Analog Switching node connection to the internal PFET switch and NFET synchronous rectifier. SGND - - 5 Ground Signal ground (feedback ground). Copyright © 2004–2014, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Links: LM3671 LM3671-Q1 |
