The TPS54560-Q1 is a 60-V, 5-A, step-down regulator with an integrated high side MOSFET.
The device survives load dump pulses up to 65 V 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 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
protects internal and external components during an overload condition.
The TPS54560-Q1 is available in an 8-pin thermally enhanced HSOIC PowerPAD package.
