The TPS40074 uses voltage feed-forward control techniques to provide good line regulation over a wide input voltage range, and fast response to input line transients. Voltage feed-forward also provides nearly constant power stage gain with input variation to ease loop compensation of wide input range designs. The externally programmable short circuit protection provides fault current limiting, as well as hiccup mode operation for low power dissipation in the presence of a shorted output. The TPS40074 is packaged in a 20-pin QFN package for better thermal performance at higher voltages and frequencies, as well as reduced footprint.
