DescriptionThe TPS57140MDRCREP device is a 42-V, 1.5-A step-down regulator with an integrated high-sideMOSFET. Current-mode control provides simple external compensation and flexible componentselection. A low-ripple pulse-skip mode reduces the no-load, regulated output supply current to 116μA. Using the enable pin reduces the shutdown supply current to 1.5 μA.
UVLO is internally set at 2.5 V, but can be increased using the enable pin. Theslow-start pin, which is also configurable for sequencing or tracking, controls the output voltagestart-up ramp. An open-drain power-good signal indicates the output is within 92% to 109% of itsnominal voltage.
A wide switching-frequency range allows optimization of efficiency and external componentsize. Frequency foldback and thermal shutdown protect the part during an overload condition.
The TPS57140MDRCREP is available in a 10-pin VSON package (DRC).
