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

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.

Individual models are available online at:

Winning Feature Set

ON Semiconductor offers a wide variety of controllers with features

to fit your application:

~

Fixed frequency current or voltage mode topologies

~

Variable-frequency Quasi-Resonant (QR) and resonant mode

architectures for higher efficiency and better EMI

~

Skip cycle, Soft-Skip™ or frequency foldback circuits for excellent

standby performance

~

Fixed on-time/variable off-time switching for low power

applications

~

Hysteretic-type control for ease of implementation

~

Comprehensive protection and safety options

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.

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.

High Voltage Technology

Very High Voltage Integrated Circuit Technology (VHVIC):

~

High speed and high accuracy control

with high voltage switching on a single

die

~

Power switching devices scalable from

200 Volts to over 1000 Volts

~

High density logic for intelligent feature-

set products

~

Medium voltage analog from 10 Volts to 60 Volts for off-line

connection and direct power switch drive
