Typical Application Circuit for ADJ version Connection Diagram and Package Mark Information Figure 3. 5-Bump MicroSMD Package Table 1. Pin Descriptions (5-Bump MicroSMD) Pin # Name Description A1 VIN Power supply input. Connect to the input filter capacitor (Figure 1). A3 GND Ground pin. C1 EN Enable pin. The device is in shutdown mode when voltage to this pin is <0.4V and enabled when >1.0V. Do not leave this pin floating. C3 FB Feedback analog input. Connect directly to the output filter capacitor for fixed voltage versions. For adjustable version external resistor dividers are required (Figure 2). The internal resistor dividers are disabled for the adjustable version. B2 SW Switching node connection to the internal PFET switch and NFET synchronous rectifier. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 2 Submit Documentation Feedback Copyright © 2006, Texas Instruments Incorporated Product Folder Links: LM3673 |
