A 4-phase monolithic synchronous boost converter that delivers 2.5A with output disconnect in a 5mm × 5mm QFN package is described.
Monolithic synchronous boost converter
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 ...
