(8) For VOUT >2. 2V, VIN min = VOUT +0.3 V (9) This time is valid if one converter turns from shutdown mode (EN2 = 0) to active mode (EN2 =1) and the other converter is already enabled (that is, EN1 = 1). In case both converters are turned from shutdown mode (EN1 and EN2 = Low) to active mode (EN1 and/or EN2 = 1) a value of typical 80 μs for ramp up of internal circuits needs to be added. After tStart the converter starts switching and ramps VOUT. 6.6 Dissipation Ratings PACKAGE POWER RATING FOR TA ≤25°C DERATING FACTOR ABOVE TA = 25°C DRC 2050 mW 21 mW/°C 6 Submit Documentation Feedback Copyright © 2007–2015, Texas Instruments Incorporated Product Folder Links: TPS62410 |
