The TPS61085 is a high frequency, high efficiency DC to DC converter with an integrated 2.0 A, 0.13
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 pin
minimizes inrush current at startup.
