Texas Instruments V62/15604-01YEThe TPS57140-EP 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. 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. The slow-start pin, which is also configurable for sequencing or tracking, controls the output voltage start-up ramp. 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-EP is available in a 10-pin VSON package (DRC).
