3 Description

The TPS54340B is a 42-V,3.5-A.step-down requlator with an intearated high side MOSFET, 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 uA. Shutdown supply current is reduced to 2 μA when the enable pin is pulled low. Underyoltage lockout is internally set at 4.3 Vbut 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
The TPS54340B is available in an 8-pin thermally enhanced HSOIC PowerPADT package.
