General Description
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.
