Description

The TPS54541DPRT is a Step-down Regulator with an integrated high-side MOSFET. The device survives load dump pulses up to 45V 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 152µA. When the enable pin is pulled low, the shutdown supply current is reduced to 2µA. Undervoltage lockout is internally set at 4.3V 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 open-drain power-good signal indicates the output is within 93 to 106% of the nominal voltage. A wide adjustable switching-frequency range allows for optimization of either efficiency or external component size. Cycle-by-cycle current limit, frequency foldback and thermal shutdown protect internal and external components during an overload condition.
