Embedded power provides true design flexibility

Two integrated switching regulators address the industry's growing need for efficient high-power-density designs.

ON Semiconductor has designed two new switching regulators to simplify embedded power supplies in high density applications.

The new level of integration provided by these devices enables customers to replace DC/DC modules with embedded designs to reduce system cost while increasing power density.

According to an industry report by Darnell Group, DC/DC modules in the 5 to 10A range are experiencing the greatest dynamics and market growth.

While the market for nonisolated DC/DC convertor modules in this range is either declining or experiencing slowed growth, the integrated convertor/regulator IC market, is expected to grow 16% between 2006 and 2011.

The NCP3102 and NCP3101 are both integrated switching regulators that address the industry's growing need for efficient high-power-density designs.

NCP3102 is a 10A synchronous switching regulator that enables high efficiency power conversion from a +5 or +12V supply.

The internal 8mohm high-side FET and 8mohm low-side FET enable efficiencies greater than 92% for typical buck applications.

The NCP3102 also features an internal voltage reference of 0.8V for sub-1V operation now required.

NCP3101 is a 6A synchronous switching regulator that is pin compatible with the NCP3102.

This pin compatibility allows design engineers to scale their power solutions without having to redesign their printed circuit board (PCB).

In many designs that use an FPGA for example, the final power requirements are not known until late in the design cycle.

By offering true design flexibility, the NCP3101 allows the design engineer to scale up or scale down the power requirement based on the system need.

"The NCP3101 and NCP3102 enable our customers to quickly and easily reduce the cost of their systems by simply switching from an existing DC/DC module to an embedded design", says Tim Kaske, ON Semiconductor Product Line Marketing Manager for the Power Regulation Product Group.

"This is especially true in FPGA designs where the current consumption is typically higher and our customers currently use a DC/DC module or other expensive integrated solution".

"In some cases, we have helped our customers reduce their system cost by as much as 50% with our new solution".

The NCP3102 and NCP3101 are available in commercial temperature grade as well as industrial temperature grade as the NCP3102B and NCP3101B.

The NCP3102 and NCP3101 are offered in 6 x 6mm QFN packages and priced at US $1.90 and $1.75, respectively, per unit in 10,000-unit quantities.
