Hot-selling and scarce TPS54622RHLR 4.5-V to 17-V Input, 6-A Synchronous Step-Down Converter 14VQFN spot stock

Product Descriptions

The TPS54622 device in thermally enhanced 3. 5-mm× 3. 5-mm VQFN package is a full-featured 17-V, 6-Asynchronous step-down converter optimized for smalldesigns through high efficiency and integrating thehigh-side and low-side MOSFETs .   Further  spacesavings are achieved through current mode control,which reduces component count, and by selecting ahigh switching frequency, reducing the footprint of theinductor .

​The output voltage start-up ramp is controlled by theSS/TR pin, which allows operation as either a standalone power supply or in tracking situations .  Powersequencing is also possible by correctly configuringthe enable and the open-drain power good pins .

Cycle-by-cycle current limiting on the high-side FETprotects the device in overload situations and isenhanced by a low-side sourcing current  limit  thatprevents current  runaway . There is also a low-sidesinking current   limit   that   turns off  the low-sideMOSFET to prevent   excessive reverse current .Hiccup protection is triggered if  the overcurrentcondition has persisted for longer than the presettime . Thermal  hiccup protection disables the devicewhen the die temperature exceeds the thermalshutdown temperature and enables the part  againafter the built-in thermal shutdown hiccup time .
