Texas Instruments  TPS61085TDGKRQ1

The TPS61085-Q1 device is a high-frequency, high-efficiency, DC-DC boost converter with an integrated 2-A, 0.13-Ω power switch capable of providing an output voltage up to 18.5 V. The selectable frequency of 650 kHz or 1.2 MHz allows the use of small external inductors and capacitors, and provides fast transient response. The external compensation allows optimizing the regulator for application conditions. A capacitor connected to the specific soft-start pin minimizes inrush current at start-up.
