3 Description

The TPS61085 device is a high-frequency highefficiency

DC-to-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.
