The CXSU63033 is high efficiency synchronous, 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 minimizes overall solution footprint by allowing the use of tiny,low profile inductors and ceramic capacitors.
The CXSU63033 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.
