Figure 1. Efficiency at VOUT = 4.5 V (Forced PWM Mode) Figure 2. Efficiency at VOUT = 4.5 V (Auto Mode) Figure 3. Efficiency at VOUT = 5 V (Forced PWM Mode) Figure 4. Efficiency at VOUT = 5 V (Auto Mode) (4) CIN and COUT: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) used in setting electrical characteristics. COUT_MIN should not exceed −40% of suggested value. The preferable choice would be a type and make MLCC that issues –30% over the operating temperature and voltage range. 6 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Product Folder Links: LM3668-Q1 |
