TPS54360DDAR

The TPS54360 is a 60-V, 3.5-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 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.
Frequency foldback and thermal shutdown protect
internal and external components during an overload
condition.
The TPS54360 is available in an 8-terminal thermally
enhanced HSOIC PowerPAD™ package.
