TPS54040 Datasheet - Texas Instruments

TPS54040 42-V Step Down DC/DC Converter

The TPS54040 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 output supply current to 116 μA. Using the enable pi.
