TPS54160QDGQRQ1

Product Summary

The TPS54160QDGQRQ1 is a 60-V 1.5-A step-down regulator with an integrated high-side MOSFET. Current-mode control provides simple external compensation and flexible component selection. A low-ripple pulse-skip mode reduces the no load, regulated output supply current to 116 μA. Using the enable pin, shutdown supply current is reduced to 1.3 μA. Undervoltage lockout is set internally at 2.5 V but can be increased using the enable pin. The output voltage startup ramp of the TPS54160QDGQRQ1 is controlled by the slow start pin that can also be configured for sequencing/tracking. An open-drain power good signal indicates the output is within 93% to 107% of its nominal voltage. The applications of the TPS54160QDGQRQ1 include 12-V, 24-V, and 48-V Industrial and Commercial, Aftermarket Automotive Accessories: Video, GPS, Entertainment.
