SLVSBO1F – JULY 2013 – REVISED FEBRUARY 2017 TPS54561 4.5-V to 60-V Input, 5-A, Step-Down DC-DC Converter
with Soft-Start and Eco-modeв„ў
1 Features 3 Description The TPS54561 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 152 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
