(5) Output voltage specification does not include tolerance of external voltage programming resistors (6) Configuration L typ 2.2mH, COUT typ 20mF, see parameter measurement information, the output voltage ripple in PFM mode depends on the effective capacitance of the output capacitor, larger output capacitors lead to tighter output voltage tolerance. (7) In Power Save Mode, PWM operation is typically entered at IPSM = VIN/32Ω. (8) For VOUT > 2V, VIN min = VOUT +0.5V (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 (e.g., 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 typ 80 ms for ramp up of internal circuits needs to be added. After tStart the converter starts switching and ramps VOUT. 4 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s) :TPS62404-Q1 |
