Texas Instruments  TPS54560DDA

The TPS54560 is a 60 V, 5 A, step down regulator with an integrated highside MOSFET. The device survives load dump pulses up to 65V per ISO 7637. Current mode controlprovides simple external compensation and flexible component selection. A low ripple pulse skipmode reduces the no load supply current to 146 µA. Shutdown supply current is reduced to 2 µA whenthe enable pin is pulled low.

Undervoltage lockout is internally set at 4.3 V but can be increased using the enablepin. The output voltage start up ramp is internally controlled to provide a controlled start up andeliminate overshoot.

A wide switching frequency range allows either efficiency or external component size tobe optimized. Output current is limited cycle-by-cycle. Frequency foldback and thermal shutdownprotects internal and external components during an overload condition.

The TPS54560 is available in an 8-terminal thermally enhanced HSOPPowerPAD™ package.
