SLVSDP8 – FEBRUARY 2017 TPS54560B-Q1 4.5 V to 60 V Input, 5 A, Step Down DC-DC Converter with Eco-mode™
1 Features 3 Description The TPS54560B-Q1 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 ОјA. Shutdown supply current is
reduced to 2 ОјA when the enable pin is pulled low. 1 High Efficiency at Light Loads with Pulse Skipping
