ON Semi Introduces High Efficiency Synchronous Regulators in Compact SOIC-8 Packages
ON Semiconductor introduced a new family of high efficiency 2 to 4A integrated synchronous regulators for consumer electronics applications such as set top boxes, DVD/hard disk drives, LCD monitors/TVs, speakerphones, cable modems, and telecom/datacom equipment.
The NCP3125, NCP3126 and NCP3127 are synchronous pulse width modulation (PWM) switching buck regulators with integrated high side and low side MOSFETs capable of delivering continuous output currents of 2, 3 and 4A respectively. The new devices offer extremely low on-state resistance values
The NCP3125 has a 60mΩ high-side MOSFET and 36mΩ low-side MOSFET and provides system level efficiencies greater than 90%. All three new devices can produce output voltages as low as 0.8V from an input supply of +5 to +12V. All three devices are pin-to-pin compatible, allowing the flexibility to scale the output current up or down during the product development process or speed up the product development process by allowing quick re-use on new designs. The devices feature an operating junction temperature range of −40 to +125°C.
"These new devices allow the implementation of higher density power designs than could be achieved by using a discrete component solution consisting of a controller IC and separate MOSFETs," said John Blake, Director of the Power Switching products at ON Semiconductor. "They offer greater levels of efficiency than competing integrated regulator alternatives already on the market. As a result, engineering teams will be able to create power designs that attain higher performance benchmarks in a smaller more compact integrated solution. We see this as a key capability as customers improve their designs to meet new energy efficiency standards in various consumer electronic products."
The NCP3125, NCP3126, NCP3127 devices are offered in SOIC-8 packages and priced at $0.40, $0.35 and $0.30 per unit in 10,000 unit quantities.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
