Description
●The TPS54140 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, the shutdown supply current is reduced to 1.3 μA.
