TPS54140DGQR

1.5 A ， 42V降压SWIFT ™ DC / DC具有Eco-Mode ™转换器 1.5-A, 42V STEP DOWN SWIFT™ DC/DC CONVERTER WITH ECO-MODE™

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.
