Exar公司宣布XRP7674的可用性,一個新的同步脈沖頻率調(diào)制和脈沖寬度調(diào)制(烤瓷/ PWM)下臺電壓調(diào)節(jié)器,最大負(fù)載電流2安培和操作輸入電壓18 v。
Exar Corporation announced the availability of theXRP7674, a new synchronous Pulse Frequency Modulation/Pulse Width Modulation (PFM/PWM) step down voltage regulator with a maximum load current of 2 Amps and operating input voltage up to 18V.
This latest addition to Exar’s PowerBloxTM family of high voltage, high current step down regulators, provides customers with a compact and integrated solution with improved light load efficiency, achieving better than 90% efficient conversions for output current as low as 50mA. TheXRP7674 is optimized for 5V and 12V inputs and addresses the needs of energy efficient equipment and the latest Energy Star regulations. This includes audio-video equipment such as set-top boxes and gaming systems, telecom, computing peripherals, distributed point-of-load conversions and portable applications where light load efficiency is essential.
“Energy efficient products are not only
Product Information
The XRP7674 is a synchronous current mode PFM/PWM step down (buck) regulator capable of delivering a constant output current up to 2Amps. Reaching up to 95% efficiency, it achieves greater than 85% efficient conversions over a 30mA to 2A load current range. The XRP7674 operates at a fixed 340 kHz switching frequency, with output voltage adjustable down to 0.925V with +/- 2% accuracy across the entire operating range. A dedicated enable pin and programmable soft start provide design flexibility for any point-of-load supply. Built-in current limit, output over voltage and thermal shutdown protection provide theXRP7674 with fail-safe operations. The XRP7674 offers a package equivalent upgrade to Exar’s popular XRP7664.
Product Availability
The XRP7674 is available now and customers can purchase the product through authorized distributors or by going to the Exar website and selecting “order samples”. The XRP7674 comes standard in a RoHS compliant, Halogen Free 8-Pin SOIC Package. Pricing for the XRP7674, in 1,000 unit quantities, starts at $0.89 per unit.
Additional information on the XRP7674 is available online. Additional information on Exar’s power management products is also available online.
