Product Summary

The TPS61085DGKR is a high frequency, high efficiency DC to DC converter with an integrated 2.0 A, 0.13Ω power 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 connected to the soft-start pinminimizes inrush current at startup. The applications of the TPS61085DGKR include Handheld Devices, GPS Receiver, Digital Still Camera, Portable Applications, DSL Modem, PCMCIA Card, TFT LCD Bias Supply.
