HX3001

HX1001 HX3001 Synchronous Boost DC/DC Regulator Features Up to 94% Efficiency Low voltage start-up 0.9V Description ： ～ Output voltage：2.5V～4.3V (Up to 5V with Input voltage 0.9V 4.4V Schottky) Low switch on resistance RDS(ON), Internal switch: 0.35 Shut-down current: < 1µA ： 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 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 HX3001 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 HX3001 regulators are available in the industry standard SOT-23-6 power packages (or upon request).
