Merci beaucoup! - ROHM receives Electrons D´Or 2018 award in Paris

08/01/2018

The Trocadéro consists of several gardens and buildings which were built for the 1937 Universal Exhibition. It is located in the 16th arrondissement, near the Eiffel Tower, and offers an imposing view of the river Seine. Also situated in this district is the Palais de Chaillot with its various museums, gardens and an underground aquarium.

Naturally, this area is popular with tourists as well as Parisians providing opportunities for picturesque walks, but we digress. ROHM was delighted to have been invited to join a special occasion as one of the nominees for a major award given by the French electronics industry.

The 21st edition of the Electrons d'Or, organized by the journal ElectroniqueS, was held on Tuesday, June 26, 2018, in Paris, in the presence of leading players in the French electronics industry. The awards once again acknowledged the best products, applications and company of the year in their respective categories. A jury of well-known industry experts as well as the editorial staff of the publication Electroniques met on May 28, in Boulogne-Billancourt to nominate the winners in the 13 categories. ROHM semiconductor was nominated in three of them: Analog/mixed circuits, Automotive, Connected Objects/Smart buildings. Finally Alexandre Bueno, Automotive Account Manager in our French team was asked to come on stage and receive the award in the category analog/mixed circuits for our NanoPulse DC/DC (BD9V100MUF-C).

The BD9V100MUF-C, a DC/DC converter with built-in MOSFET that can generate output voltages of just 3.3 V or 5 V (minimum 2.5 V) from input voltages up to 60 V at a switching frequency of 2 MHz. The IC therefore achieves the highest step-down ratio in the industry – 24:1 – between input and output voltages.

To date, no power supply IC has achieved both a high conversion ratio and a high switching frequency. A two-stage solution meets these requirements, but has various disadvantages: It takes up more space, uses more components, and is a more complex system. With the BD9V100MUF-C, ROHM is offering a single-stage voltage conversion solution.

To obtain this voltage ratio, the chip uses ROHM’s proprietary Nano Pulse Control technology, which leverages high-voltage BiDCMOS processes and ultra-high-speed pulse control to realize an unprecedented ON time of just 9 ns. The new technology enables single-stage voltage conversion in 48 V systems such as those used in mild hybrid vehicles. With a single stage solution the number of parts required is approximately halved, reducing application size and simplifying system design, while high-frequency operation also permits the use of smaller external components, e.g. coils and output capacitors.
