3 Description
The TPS54360B-Q1 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 an external resistor divider at the
enable pin. The output voltage start-up ramp is
internally controlled to provide a controlled start up
and eliminate overshoot.
A wide adjustable frequency range allows either
efficiency or external component size to be optimized.
Frequency foldback and thermal shutdown protects
internal and external components during an overload
condition.
The TPS54360B-Q1 is available in an 8-pin thermally
enhanced HSOP PowerPAD package.
