Texas Instruments TPS54361DPRT TPS54361DPRT DC-DC Switching Buck (Step Down) Regulator Adjustable 4.5V-60Vin 800mV-59Vout 3.5Aout WSON-10

The TPS54361DPRT is a 3.5A Step-down DC-DC Converter with soft-start and Eco-mode�. The device survives load dump pulses up to 65V 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. Shutdown supply current is reduced to 2µA when the enable pin is pulled low. Under-voltage lockout is internally set at 4.3V but can increase using an external resistor-divider at the enable pin. The output voltage start-up 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.
