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.
