The TPS54560 is a 60 V, 5 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 146 µA. Shutdown supply current is reduced to 2 µA when
the enable pin is pulled low.Undervoltage lockout is internally set at 4.3 V but can be increased using the enable
pin. The output voltage start up ramp is internally controlled to provide a controlled start up and
eliminate overshoot. A wide switching frequency range allows either efficiency or external component size to
be optimized. Output current is limited cycle-by-cycle. Frequency foldback and thermal shutdown
protects internal and external components during an overload condition.The TPS54560 is available in an 8-terminal thermally enhanced HSOP
PowerPAD™ package.
