Applications
Description
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.
Digital cameras and MP3
Palmtop computers / PDAs
Cellular phones
Wireless handsets and DSL modems
PC cards
Portable media players
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).
