TPS57140QDRCRQ1 Datasheet PDF - TI

●The TPS57140-Q1 device is a 42-V, 1.5-A step-down regulator with an integrated high-side MOSFET. Current-mode control provides simple external compensation and flexible component selection. A low-ripple pulse-skip mode reduces the no-load, regulated output supply current to 116 μA. When the enable pin is in the low state, the shutdown current is reduced to 1.5 µA.

●Undervoltage lockout is internally set at 2.5 V, but can be increased using the enable pin. The output voltage startup ramp is controlled by the slow-start pin that can also be configured for sequencing or tracking. An open-drain power-good signal indicates the output is within 92% to 109% of its nominal voltage.

●A wide switching-frequency range allows optimization of efficiency and external component size. Frequency foldback and thermal shutdown protect the part during an overload condition.

●The TPS57140-Q1 is available in a 10-pin thermally enhanced MSOP-PowerPAD package (DGQ) and a 10-pin VSON package (DRC).
