LT3489 - 2MHz Boost DC/DC Converter

Description

of the part’s operation.

At the start of the oscillator cycle, the SR latch is set, turning on the power switch, Q1.

The switch current flows through the internal current sense resistor generating a voltage.

Features

  • LT3489 2MHz Boost DC/DC Converter with 2.5A Switch and Soft-Start.
