HXN-xH升压DC-DC，SOT23-6
HXN-xH 简单介绍
The HXN-xH 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 HXN-xH 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 HXN-xH regulators are available in the industry standard SOT-23-6 power packages (or upon request).
