TPS54541 5-A Step-Down DC-DC Converter

The TPS54541 device is a 42-V 5-A step-down regulator with an integrated high-side MOSFET. The device survives load dump pulses up to 45 V per ISO 7637. Current mode control provides simple external compensation and flexible component selection. A low-ripple pulse-skip mode reduces the no-load suppl.
