供应HC3062同步升压，低电压启动、低内阻、1-2节干电池适用

The HC3062 is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficient solution to medium power systems. The devices work under the input voltage between 0.9V and 4.4V 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 HC3062 is capable of supplying an output voltage between 2.5V and 4.3V, the internal synchronous switch is desired to provide high efficiency without Schottky. 
The devices also featured providing up to 260mA from a single AA cell input or up to 450mA from a 2-cell AA with a 3V/3.3V output. 
The HC3062 regulators are available in the industry standard SOT-23-6 power packages (or upon request).
