The TPS54340-Q1 device is a 42-V, 3.5-A, step-down regulator with an integrated high-side MOSFET. The device survives load-dump pulses up to 45 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 1 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 for optimization of either efficiency or external component size. Frequency foldback and thermal shutdown protects internal and external components during an overload condition.

The TPS54340-Q1 device is available in an 8-pin thermally-enhanced HSOIC PowerPAD package.
