The NBC12429FN is a 3.3/5.0V programmable PLL clock synthesiser that provides a 25 to 400MHz system clock ideal for the primary timing signals in networking, telecomms and test hardware.
Meritorious performance from N-channel MOSFETs
Continuing the expansion of its portfolio of low-voltage power MOSFETs for switching and power management applications, ON Semiconductor has released a range of new N-channel devices.
"ON Semiconductor focused its development efforts on producing this high-performance, cost-effective controller as part of the company's complete power solution for the rapidly changing desktop computer environment".
The NCP5210 combines two highly efficient pulsewidth modulator (PWM) buck convertors for the VDDQ supply and the MCH core voltage supply with a 2.1A source-sink linear regulator for the VTT termination voltage.
Additionally, the device offers a number of protection features including soft-start circuitry, undervoltage monitoring of conversion input voltages, thermal shutdown, and overcurrent protection.

Trench process slashes MOSFET on resistance
ON Semiconductor has developed a novel trench process technology that it claims on average delivers a 40% improvement in on-resistance when compared with other trench processes on the market today.
The overcurrent protection safeguards the DDR memory from damage due to improper insertion of a memory module.
The NCP5209 combines one PWM buck convertor for all DDR memory VDDQ, a linear source-sink for VTT, and a two-step linear solution for the MCH.
It is a cost-effective solution for motherboards requiring DDR2.
The NCP5210 and NCP5209 are offered in the compact QFN-20 package.
Selective sampling and evaluation boards are available now.
The devices are priced at $1.82 per unit in 1000-unit quantities.
Production of the devices is slated for the fourth quarter.
Additional devices in this family of integrated controllers will include varying configurations to provide computer motherboard designers the flexibility to select the best level of integration for their system based on both cost and performance.
When coupled with NTD60N02R mosfet, the NCP5210 provides a complete, scalable power solution for next-generation chipsets and DDR memory.
The low-threshold voltage of the NTD60N02R results in good conduction characteristics as low gate drive voltages.
"As CPU manufacturers push the envelope in microprocessor and computer memory design, we will work to provide them with the power-management solution that meets their aggressive development schedules", said Bernie Boland, ON Semiconductor Corporate Technical Marketing Director for Computing.
"Implementing a proven power design is preferred over spending the time and money to design and optimise a complete power system from scratch.
For this reason, ON Semiconductor offers turnkey reference designs as well as the power devices needed to implement the power solutions that virtually snap together with the latest motherboard computing building blocks".
