Active-Semi Adds New ACT451x to High Power DC-DC Converter Family
ACT451x DC-DC Converter is Ideal Design Choice for iPad/iPhone/iPod Car Charger Applications
SAN JOSE, – January 25, 2011 – Active-Semi International today released a new member of their patent-pending DC-DC converter family, the ACT451x. The device family is dedicated for iPad/iPhone/iPod car chargers and provides a complete high efficiency solution featuring accurate current limit, low standby power and fast dynamic response. With high voltage FET (field-effect transistor) built in, the ACT451x meets the requirement of 40V transparent input voltage surge for automotive applications. The family is appropriate for powering car media systems and for general DC-DC power conversion.
“The new ACT451x highlights the latest innovation in Active-Semi’s High Power products,” said Shinya Murata, Director of Active-Semi’s High Power Business Unit. “Since the ACT451x is specifically defined for iPad/iPhone/iPod car chargers, it meets all specs for the charger. Our patented output cable compensation guarantees a 5 percent voltage regulation at the end of the cable. The integrated high performance solution eliminates the need for discrete components and provides very accurate current limit. The patent-pending ActiveCC [Active Constant Current] technology eliminates the need for expensive, highly accurate current sense resistors, along with associated power loss. So it is ideal for high efficiency constant output current or high accuracy current limit applications.”
“The new DC-DC converters from Active-Semi are an excellent choice for our new product requirements,” said Jack Yin, Global Sourcing Manager, Salcomp (Shenzhen) Co., Ltd. “We are pleased with their ActiveCC technology which helps us reduce cost. This keeps us ahead of our competition while maintaining our bottom line. We continue to be impressed with the high power efficiency we are able to achieve with Active-Semi products.”
“The ACT4513 is an important part of our most innovative new designs,” said Joey Sainton, Director of Engineering, Ever Win International Group. “The conversion efficiency, fast dynamic response and low stand-by power are particularly important to us. By working with Active Semi, we are able to achieve our green initiatives without sacrificing performance.”
Active-Semi’s ActiveCC is a revolutionary technology that leverages Active-Semi’s large and growing IP portfolio to produce high-performance solutions for the industry’s DC-DC applications. Active-Semi’s ActivePSRTM family of digital Primary-Side Regulation (PSR) controllers simplify AC/DC designs for charger, adapter and LED lighting with low component-count and exceed green power efficiency and standby power standards.
