A new synchronous Pulse Frequency Modulation/Pulse Width Modulation (PFM/PWM) step down voltage regulator has been released by Exar Corporation.
This regulator has a maximum load current of 2Amps and operating input voltage up to 18V.
This latest device joins the company’s PowerBlox family of high voltage, high current step down regulators, and is said to offer improved light load efficiency, achieving more than 90 percent efficient conversions for output current as low as 50mA.
The company advises this regulator is optimised 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 about energy bill savings, they also run cooler ultimately
improving overall reliability and operation,” said Eric Pittana, Director of Marketing, Power Product Line, Exar. “The XRP7674 delivers excellent efficiency for always on points-of-load over a wide range of currents without the additional costs of other solutions.”
