TPS54560BQDDARQ1 Description

The TPS54560B-Q1 is a step-down regulator with an integrated high side MOSFET that operates at 60 V and 5 A. According to ISO 7637, the TPS54560B-Q1 can withstand load dump pulses up to 65V. Current mode control allows for simple external compensation and component selection flexibility. The no-load supply current is reduced to 146 A using a low ripple pulse skip mode. When the enable pin is pushed low, the shutdown supply current is lowered to 2 A. The enable pin can be used to increase the Undervoltage lockout, which is set to 4.3 V by default. To offer a controlled start-up and minimize overshoot, the output voltage start-up ramp is internally controlled.
