TPS54560BDDA Description

The TPS54560BDDA is a 60-volt, 5-amp step-down regulator with a high-side MOSFET incorporated. External compensation is straightforward using current-mode control, and component selection are flexible. The no-load supply current is reduced to 146 A using a low-ripple pulse-skip mode. When the EN (enable) pin is pushed low, the shutdown supply current is lowered to 2 A.
