TPS54560 DC-DC Converter with Eco-Mode™



Texas Instruments' 60 V, 5 A, step-down regulator with integrated high-side MOSFET


Texas Instruments TPS54560 DC-DC Converter with Eco-Mode™ Texas Instruments' TPS54560 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.

Under-voltage 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.
