DESCRIPTION  
The TPS54622 in thermally enhanced 3.5mm x 3.5mm QFN package is a full featured 17V, 6A synchronous step  
down converter which is optimized for small designs through high efficiency and integrating the high-side and  
low-side MOSFETs. Further space savings are achieved through current mode control, which reduces  
component count, and by selecting a high switching frequency, reducing the inductor's footprint.  
The output voltage startup ramp is controlled by the SS/TR pin which allows operation as either a stand alone  
power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and  
the open drain power good pins.  
Cycle by cycle current limiting on the high-side FET protects the device in overload situations and is enhanced  
by a low-side sourcing current limit which prevents current runaway. There is also a low-side sinking current limit  
which turns off the low-side MOSFET to prevent excessive reverse current. Hiccup protection will be triggered if  
the overcurrent condition has persisted for longer than the preset time. Thermal hiccup protection disables the  
device when the die temperature exceeds the thermal shutdown temperature and enables the part again after  
the built-in thermal shutdown hiccup time.
