LT3428
Introduction
Small size, high efficiency, low noise and simplicity are all key features for battery-powered applications and point-of-load converters in low voltage systems. The LTC3428 is well suited for these applications because it offers these features as well as minimum output ripple and component count. It can start up with as little as 1.5V and operates with inputs up to 4.5V. Its dual phase architecture allows for an effective switching frequency of 2MHz (1MHz/phase), which minimizes inductor and capacitor ...
