Product Summary

The TPS61085PWR is a high frequency, high efficiency DC to DC converter with an integrated 2.0 A, 0.13Ωpower switch capable of providing an output voltage up to 18.5 V. The selectable frequency of 650 kHz and 1.2 MHz allows the use of small external inductors and capacitors and provides fast transient response. The external compensation allows optimizing the application for specific conditions. A capacitor of the TPS61085PWR connected to the soft start pin minimizes inrush current at startup.
