產品描述
Description
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 0.6V and
4.4V with a 1.4MHz fixed frequency switching. These features minimizes overall
solution footprint by allowing the use of tiny,
low profile inductors and ceramic
capacitors.
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.
in the industry standard SOT-23-6 power
packages (or upon request).
