The resulting output voltage drops to ≈40% of its nominal value, causing the average power dissipated by the IC to lower. (2) Output is not connected to diode, inductor, or capacitor. Output is sourcing current. (3) FEEDBACK is disconnected from output and connected to 0 V. 6 Submit Documentation Feedback Copyright © 2006–2014, Texas Instruments Incorporated Product Folder Links: TL2575 TL2575HV |
