Product Summary

The TPS5633PWP is a synchronous-buck regulator controller provides an accurate supply voltage to DSPs. The output voltage of the TPS5633PWP is internally set by a resistive divider with an accuracy of 1% over the full operating temperature range. A hysteretic controller with user-selectable hysteresis is used to dramatically reduce over shoot and under shoot caused by load transients. Propagation delay from the comparator inputs to theoutput drivers is less than 250 ns. Overcurrent shutdown and crossover protection for the output drivers combine to eliminate destructive faults in the output FETs.
