FSP3602
„ GENERAL DESCRIPTION
The FSP3602 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 0.6V 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.
The FSP3602 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 180mA from a
single AA cell input or 400mA from a 2-cell AA with a
3V/3.3V output.
The FSP3602 converter is available in the industry
standard SOT23-6L power packages (or upon
request).
