| 品牌/商标： | SY |
The SY3131 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 improve efficiency.
The SY3131 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 600mA from a 2-cell AA with a 3V/3.3V output.
The SY3131 regulators are available in the industry standard SOT-23-6 power packages (or upon request).
