TPS61086EVM-526: 12V @ 300mA, 9 ~ 18.5V in

Summary

The TPS61086 is a high-frequency, high-efficiency, DC-to-DC converter with an integrated 2-A, 0.13-Ω power switch capable of providing an output voltage up to 18.5 V. The frequency of 1.2 MHz allows the use of small external inductors and capacitors and provides a 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 start-up.

At light load, the device can operate in Power Save Mode with pulse-frequency-modulation (PFM) to improve the efficiency while keeping a low output voltage ripple. For very noise sensitive applications, the device can be forced to PWM Mode operation over the entire load range by pulling the MODE pin high. The external compensation allows optimizing the application for specific conditions. A capacitor connected to the soft-start pin minimizes inrush current at startup.
