产品概述 返回TOP
The CXSU6314 is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficient
solution to medium power systems. The devices work with a 1.4MHz fixed frequency switching. These features minimize
overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Automatic PWM/PFM
mode switching at light load saves power and improves efficiency.
The CXSU6314 is capable of supplying an output voltage between 2.5V and 5V, the internal synchronous switch is
desired to provide high efficiency without Schottky.
The CXSU6314 regulators are available in the industry standard SOT-23-6L power packages (or upon request).
