The TPS4007x uses voltage feed-forward control techniques to provide good line regulation over a wide-input
voltage range, and fast response to input line transients with near constant gain with input variation to ease loop
compensation. The externally programmable short circuit protection provides fault current limiting, as well as
hiccup mode operation for thermal protection in the presence of a shorted output.The TPS4007x is packaged in a
16-pin PowerPAD package for better thermal performance at higher voltages and frequencies. See SLMA002 for
information on board layout for the PowerPAD package. The pcb pad that the PowerPAD solders to should be
connected to GND. Due to the die attach method, the PowerPAD itself cannot be used as the device ground
connection. The two device grounds must be connected as well.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
