Enpirion Introduces New Family of PowerSoC Voltage Mode Synchronous Buck DC-DC Converters

Enpirion announced the availability of its new EN6300 family of voltage mode synchronous buck dc-dc converters: the 3A EN6337QI, 4A EN6347QI, 8A EN6360QI, and 12A EN63A0QI. These low-power switch-mode converters are complete power systems on a chip (PowerSoC), achieving up to 96% efficiency and integrating the inductor, power switches, gate drive, controller, and loop compensation.

Enpirion states that it continues to enhance its established power chip architecture to achieve a record 113W per square inch solution power density (17.6W/cm2). According to the company, the EN6300 family delivers an improvement over alternative solutions, including modules, by delivering up to 5% higher efficiency (1.2W power savings), up to 83% circuit board area reduction, and up to a 68% cost reduction, while providing lower power supply noise and operating at full load over the entire operating temperature range.

According to Enpirion, leading OEMs are widely adopting these devices because they meet the high efficiency, low noise, precise voltage and fast transient requirements of high-performance applications powering field programmable gate arrays (FPGAs), microprocessors, digital signal processors (DSPs), ASICs, and other dc-dc point of load (POL) devices. Key POL applications include blade servers, RAID storage systems, LAN/SAN adapter cards, wireless base stations, industrial automation, test and measurement, embedded computing, communications, and multi-function printers.

EN6300 family features and benefits include: input voltage from 2.375 to 6.6V – customers may also use Enpirion’s 12V high efficiency (97.5% peak) intermediate bus converter (EC2630) to front-end these devices for 12V applications; flattened efficiency profile from 20 to 100% load, permitting designers to manage power effectively over their entire operating range; full load operation across the entire ambient temperature range from -40 to +85°C, without the need for airflow or heat sink; low ripple and EMI (CISPR 22 Class B compliant); and phase-locking for input clock synchronization to reduce input ripple and remove beat frequencies.

"Design engineers and architects are finding the addition of the 3A to 12A EN6300 family of devices to Enpirion’s DC-DC PowerSoC family to be the answer to many of the difficult design challenges they have been facing," said Mark Cieri, Director of Marketing and Business Development at Enpirion. "Our combination of high performance, low noise, smallest footprint, and affordable solution cost has impressed our customers, and paved the way for efficient, cost-effective product improvements."

Enpirion’s EN6300 power devices are sampling now, with pricing set at $2.71 for EN6337, $3.43 for EN6347, EN6360 at $6.64, and EN63A0 at $10.00 in quantities of 1000 parts.
