Beschreibung
The TPS61085 is a high-frequency high-efficiency dc-to-dc converter with an integrated 2.0-A 0.13-Ωpower switch capable of providing an output voltage up to 18.5 V. The selectable frequency of 650 kHz and 1.2 MHzallows 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 connected to the soft-start pin minimizes inrush current at startup.
