TPS54540BQDDARQ1 Product Details
The TPS54540BQDDARQ1 is a42-V, 5-A step-down regulator with anintegrated high side MOSFET. Current-mode control provides simple external compensation andflexible component selection. A low-ripple pulse-skip mode reduces no-load-supply current to 146μA. Shutdown supply current is reduced to 2 μA when the EN (enable) pin is pulled low.
Undervoltage lockout is internally set at 4.3 V but can be increased using the EN pin.Output voltage start-up ramp is internally controlled to provide a controlled start-up andeliminate overshoot.
A wide switching frequency range allows either efficiency or external component size tobe optimized. Output current is limited cycle-by-cycle. Frequency foldback and thermal shutdownprotects internal and external components during an overload condition.
The TPS54540BQDDARQ1 isavailable in an 8-pin thermally enhanced HSOIC PowerPAD package.
