The models in the Power IC Model Library are compared and verified
with bench data under startup, steady state, line, and load transient
conditions. Nonlinear characteristics such as propagation delay,
switching speed, drive capability, maximum duty cycle/current limits,
and startup phenomena are all accurately modeled. Designers can
directly compare the performance of components from various vendors and
analyze the effects of different implementations such as peak current
mode control, hysteric current control, low voltage, and low operating
current, to name just a few.
Power IC Model Library key benefits:
Being an important and
key semiconductor part, power management is crucial to portable
devices. Power management IC usually consists of integrated type and
separate type. Of which, the former can be called as PMU. In a
multimedia player, the price of power management IC is only behind that
of core decoding chip. In a handset, the cost of power management IC
ranks the third after baseband and memory.
When it comes to
portable electronic devices nowadays, handsets has the most shipment.
Thereby, the market of handset power management IC draws much attention
from lots of manufacturers.
PMU is the key component
essentially necessary for handset semiconductor platform. Any
manufacturer of mobile phone semiconductor platform owns PMU
technologies and products, which is significantly valuable for domestic
handset semiconductor manufacturers. In the field of handset baseband,
manufacturers such as Spreadtrum and T3G etc should realize that
handset semiconductor; baseband in particular, must carry out platform
strategy. Only platform strategy could meet quicker shipment, lower
cost and better performance. Besides baseband, MPU and RF are
necessarily required as well.
Connection between Handset PMU and Handset Function Modules

Each function module in handsets requires interactive cooperation of divers PMU devices.

Power management system in mobile phone is illustrated below.

At
present, while light LED drive and PMU are prevalent in handset power
management. It is easy for manufacturers to access into LDO field.
However, market opportunities are shrinking as the successive entry of
Taiwanese manufacturers. In addition, more and more LDO are integrated
in mobile phone PMU. Thus, experts advise to look on in LDO field.
DC/DC converter system is also integrated in PMU. Nevertheless, it is
hard to be integrated into digital camera and DV in which motor drive
part resides. The purchasing rights for digital camera and DV groupware
are almost under control of Japanese and South Korean manufacturers.
Thereby, experts also advise to look on.
At present, 30 manufacturers or so are involved in the production of white-light LED drive IC worldwide.

With
regard to handset PMU, it is a kind of IC which is integrated with
several DC/DC converters (always 2-3), LDO (always 6-14), protection
circuit and electric capacity test, etc.
PMU merits
lie in the simplified designing and less area covered in PCB board due
to reduced components. PMU defects: 1. Low upper limit of supporting
voltage; 2. inflexible application; 3. high cost.
PMU
is mainly applied to the products with long lifecycle, single module
and large shipment, such as smart mobile phone, PDA and IPOD. But
domestically manufactured handsets are as usual changed externally
instead of internally, mainboard in particular. Thus, the prospect of
PMU is still promising.
There is another kind
of PMU aiming at MP3, digital camera and PMP. For MP3 player
manufacturers with more attention on dimensions and power consumption,
integrated PMU is better than separate power management IC. As the
focus of MP3 market rests with product price, manufacturers are mainly
concerned about costs, resulting in few PMU for MP3 player in the
market. However, MP3 competition, especially high-end MP3 will be of
more size, more function and performance in the future. Therefore,
power management IC aiming at MP3 still has growth potential. In
addition, it is easy for manufacturers to enter this field because
power management IC of MP3 player is comparatively simple. Currently,
competition of this market is not so intense.
