6 / 40 page  TPS2540, TPS2540A TPS2541, TPS2541A SLVSAG2C – OCTOBER 2010 – REVISED OCTOBER 2011 www.ti.com ELECTRICAL CHARACTERISTICS (continued) Conditions are -40 ≤ TJ ≤ 125°C unless otherwise noted. VEN (if TPS2540 or TPS2540A) = VDSC (if TPS2541 or TPS2541A) = VIN = 5 V, RFAULT = 10 kΩ, RILIM0 = 210 kΩ, RILIM1 = 20 kΩ, ILIM_SEL = 0 V, CTL1 = CTL2 = GND, CTL3 = VIN (TPS2540/40A) or CTL3 = GND (TPS2541/41A), unless otherwise noted. Positive currents are into pins. Typical values are at 25 °C. All voltages are with respect to GND unless otherwise noted.
