產品概述
The TPS54540QDDAQ1 is a Step-down Regulator with an integrated high-side MOSFET. 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 146μA. Shutdown supply current is reduced to 2μA when the enable pin is pulLED low. Undervoltage 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 either efficiency or external component size to be optimized. Output current is limited cycle-by-cycle. Frequency foldback and thermal shutdown protect internal and external components during an overload condition.
