Deviation is calculated by the formula: (2) The deviation of the OUT0–OUT15 constant-current average from the ideal constant-current value. Deviation is calculated by the following formula: Ideal current is calculated by the formula: (3) Line regulation is calculated by this equation: (4) Load regulation is calculated by the equation: 4 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s): TLC59282 |
