HX3001数据手册HXSEMI中文资料规格书

描述 Description

The HX3001 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.\r
\r
The HX3001 is capable of supplying an output voltage between 2.5V and 5V, the internal synchronous switch is desired to provide high efficiency without Schottky.\r
\r
The HX3001 regulators are available in the industry standard SOT-23-6L power packages (or upon request).
