Santa Clara, Calif., November 29, 2012 — Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, has developed the RAA20770X Series of mini-POL [Note 1] converters for ASICs and other large-scale logic circuits in a wide variety of application fields, including personal computers, servers, industrial, office automation and networking equipment. The RAA20770X Series devices achieve the industry´s highest level of miniaturization and power density. Renesas is now releasing six products with different current supply ratings and functionality.
Recently, there have been two changes in power supplies market. The first is the requirement for reduced power consumption to achieve an energy-saving society, and the second is the increasing diversity in supply voltages required by increasingly highly functional semiconductor products such as microcontrollers (MCUs) and SoC devices.
To satisfy the first requirement, the new RAA20770X devices perform high-efficiency power conversion during normal load and – typically 90 percent of the time – also execute the frequent transitions to low-power mode quickly. As a result, they reduce overall system power consumption and help enable an energy-efficient society.
To satisfy the second requirement, although mounting area is spreading according to electric source increasing, the RAA20770X devices achieve a size reduction of about 75 percent compared to earlier Renesas products, featuring an ultra-miniature wafer-level chip size package that is essentially the same size as the chip itself. Furthermore, since no wired connections are required within the package, resistance in the wiring is reduced, which contributes to more efficient voltage conversion. The RAA20770X Series represents the first devices with this level of integration in this small a package size.Key Features of the RAA20770X Series POL Converter ICs:
In addition to combining the power supply controller and driver controller IC, the RAA20770X Series devices integrate, on a single chip, two power MOSFETS [Note 3] that are optimal for POL converters that step down an input voltage of 5 V or 12 V to the 1 V or 3.3 V used by large-scale ICs such as ASICs. For example, the RAA207701GBM device features a maximum rated current of 10 A, and for a 12 V input and 3.3 V output, it can achieve high-efficiency power conversion from the low-current area to the high-current area - in particular, an 89 percent efficiency at 10 mA, a 95 percent efficiency at 4 A, and a 92 percent efficiency at 10 A . This power conversion efficiency, contributes to lower power overall in end-use products.
Samples of the RAA20770X Series POL Converter ICs will start in December 2012. While the sample price for these new products will differ depending on the output capacity, the sample price for the RAA207700GBM with a maximum rated current of 15 A will be US$2.05 per unit. Mass production of the RAA20770X devices is scheduled to begin in March 2013 and is expected to reach a scale of 500,000 units per month in July 2013.
