The proper gain for maintaining regulation is chosen so that efficiency is maximized over the input voltage range. LM2751 uses constant frequency pre-regulation to minimize conducted noise on the input and provide a predictable switching frequency. The switching frequency is programmable to 725kHz, 300kHz, 37kHz, or 9.5kHz. LM2751 is available in a 10-pin SON No-Pullback Package. Connection Diagram Figure 1. 10-pin SON No Pullback Package (3mm × 3mm × 0.8mm) See Package Number DSC0010A PIN DESCRIPTIONS Pin # Name Description 1 VOUT Pre-Regulated Output. 2 C1+ Flying Capacitor C1 Connection. 3 VIN Input Supply Range: 2.8V to 5.5V. 4 CS0 Frequency Select Input 0. 5 CS1 Frequency Select Input 1. 6 EN Enable Pin Logic Input. 7 C2− Flying Capacitor C2 Connection. 8 GND Ground. 9 C1− Flying Capacitor C1 Connection. 10 C2+ Flying Capacitor C2 Connection. 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 © 2005–2013, Texas Instruments Incorporated Product Folder Links: LM2751 |
