Description

The TPS54541DPRR,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 supply current to 152 μA. When the enable pin is pulled low, the shutdown supply current is reduced to 2 μA . Undervoltage lockout is internally set at 4.3 V but can increase using an external resistor divider at the enable pin. The output voltage startup ramp is controlled by the soft-start pin that can also be configured for sequencing and tracking. An opendrain power-good signal indicates the output is within 93% to 106% of the nominal voltage.
