Introduction
The LTC3425 is the industry’s first 4-phase, monolithic synchronous boost converter. It can start up with as little as 1V and operate with inputs up to 4.5V. The output voltage range is 2.4V to 5.25V, making it well suited for battery-powered applications as well as point-of-load regulation in low voltage systems. The 4-phase architecture allows for an effective switching frequency of up to ...
