Power Conversion Solutions from ON Semiconductor
ON Your Way to Designing Efficient Power Supplies. . .
Designing world-class power supplies is getting harder. Every year, your customers demand more power from
a smaller space at a lower cost. In addition, new regulations are imposing increasingly stringent requirements
on power conversion efficiency, quality, and standby consumption.
ON Semiconductor provides a diverse portfolio of power management solutions to meet the needs of designers
worldwide. Our products help you produce more power in a smaller footprint while meeting power consumption specifications such as
Energy Star® and Blue Angel*, and PFC requirements such as IEC1000-3-2.

ON Semiconductor covers the complete power chain, from industrial power supplies to consumer applications such as DVD players, set
top boxes, computers, laptops and cell phones.

SPICE Models Available
Reach the Minimum. . .
ON Semiconductor offers full power
solutions with dedicated SPICE models
implemented in a working template. Both
transient simulations and small-signal
analysis help you test your design quickly and
safely - before you get out the soldering iron. In partnership with
Intusoft®, our free demonstration kit lets you simulate working
applications from wall adapters to multi-output power supplies.
Complying with existing and future energy conversion
regulations can be challenging. Power controllers
and switching regulators from ON Semi-conductor
minimize standby power consumption and maximize power
conversion efficiency. For example, a 70 W power supply
reference design built with the NCP1203 has been
shown to consume only 86 mW at no-load conditions
— the best performance in its class.
Individual models are available online at:
http://www.onsemi.com/support/models/powermanagement
Or order the SPICE Simulation CDROM at:
http://www.onsemi.com/orderlit
For two consecutive years, ON Semiconductor has
been the only chip manufacturer recognized by the
China Standard Certification Center (CSC, formerly
the CECP) to support China’s drive for standby
power reduction and energy conservation. We are participating
in European Commission (EC) work groups developing a Code
of Conduct to help reduce standby losses in a wide range of
consumer equipment.

Power Factor Controllers
Minimize THD and Maximize PF and Efficiency. . .
IEC 1000-3-2 standards set regulations to limit the harmonics injected into the AC line by any equipment drawing
more than 75 W of input power for class D equipment (TV sets, PC monitors, desktop PCs) and 25 W for class C
equipment (lighting). A front-end Power Factor Controller is then required in these power supplies. Adding such a
stage can lead to difficulties in meeting other regulatory requirements (standby and active power) unless you make
judicious design choices.
Above challenges have been fully understood by ON Semiconductor which steadily releases innovative PFC controllers matching designers’
wishes of simple, compact and robust solutions. These new PFCs represent perfect solutions in various applications such as Flat TVs, ATX
Power supply & Servers, Telecom and Industrial SMPS where cost will, of course, always be a primary factor, but where you can also base
differentiation on performance.

Variable Frequency Controllers
Minimum EMI, Maximum Efficiency. . .
ON Semiconductor’s variable frequency controllers include quasi-resonant and resonant controllers.
These controllers are used respectively in critical conduction mode quasi-resonant flyback converters
and half bridge resonant LLC converters. These topologies minimize EMI radiation, provide better
magnetic utilization and offer excellent power conversion efficiency - up to 90%. Our variable
frequency controllers combine the advantages of working directly off-line (with our proprietary
VHVIC technology) with the ability to drive an external high-voltage MOSFET of your choice, and
offer you more design flexibility than our competitors.
