TPS54040A Datasheet PDF - TI

●DESCRIPTION

●The TPS54040A device is a 42 V, 0.5 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 input supply current to 116 μA. Using the enable pin, shutdown supply current is nominally 1.3 μA when the enable pin is low.
