FDK CORPORATION developed, which are the smallest-in-the-world size suited
for a variety of mobile apparatus such as the 3rd generation cellular phone
, digital camera, and PDA.
This product is the module allowing for transformation of voltage required
by each load circuit provided from the power supply of mobile apparatus,
and it is ideally designed for the 3rd generation cellular phones, such
as W-CDMA, realizing the conversion of the voltage (3.6V) of a lithium
ion battery into voltage (about 1.0-2.5 V) required by DSP (digital signal
processor), power amplifier, etc.
Corresponding to advanced features of high speed of information processing,
large-sized, colorization of a display, etc., the more efficient electric
power which enables prolonged use of a battery is called for. The micro
DC-DC converters, "GM series", have realized the highest conversion
efficiency (96%) for the required voltage while providing the capacity
of 0.018 cc (electric power density 68.1W/cc) with the smallest-in-the-world
size .
In this new developed technology, the performance of inductor, which
is the core of a converter, was further enhanced. It now offers the features
of fine printing technology, CAE (Computer Aided Engineering), depression
of high noise and high-density mounting as well as the low loss high power
function by making full use of low loss ferrite material technology.
The micro DC-DC converter was realized in smallest-in-the-world size by effectively incorporating and concentrating on circuit technology, high-density mounting technology, etc. which have been cultivating until now in addition to development of this inductor.
The mass-production of this product is expected to start from the spring
of 2003 towards a mobile apparatus market and it will be exhibited at "CEATEC
JAPAN 2002" held from October 1.
