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 lo...
