TPS54561DPRT

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4.5В-60В (Vin), 800мВ-59В, 5А, WSON-10.

The TPS54561DPRT is a 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/tracking. An open drain power good signal indicates the output is within 93 to 106% of its 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 protects internal and external components during an overload condition.
