DESCRIPTION  
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-pin thermally enhanced HSOIC PowerPAD™ package.
