TPS54340QDDAQ1

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4.5В-42В (Vin), 800мВ-41В, 3.5А, PPAD-8.

The TPS54340QDDAQ1 is a 42V 3.5A Step-down Converter with an integrated high-side MOSFET and Eco-mode™. 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, regulated output supply current to 146µA. Using the enable pin, shutdown supply current is reduced to 1µA, when the enable pin is low. Under-voltage lockout is internally set at 4.3V but can be increased using an external resistor divider at the enable pin. The output voltage start-up ramp is internally controlled to provide a controlled start-up and eliminate overshoot. A wide adjustable frequency range allows for optimization of either efficiency or external component size. Frequency foldback and thermal shutdown protects internal and external components during an overload condition.
