* Ultra-integrated DC-to-DC converter for Point of Load (POL) applications
* 10W of output power; 3A of output current; Up to 90% efficiency
* Switching frequencies of 5X to 10X over competitors
Bloomsbury, NJ, May 25, 2004 - Enpirion, Inc. today announced the introduction of the world's smallest Power System on a Chip (PSoC) and the world's fastest synchronous buck converter. The EN5330 is the first of the iPOWERTM line of integrated DC-to-DC converters for use in Point of Load (POL) applications including servers, personal computers, laser printers, set-top boxes, and telecommunications and data communications equipment. Enpirion, a fabless semiconductor company founded in 2001, has been engaged in extensive R&D on integrated power technologies leading up to the market-release of its first product.
Enpirion's disruptive technology will change the way development engineers approach supplying and managing power in a wide variety of products. The EN5330 - the first to feature an integrated inductor - reduces real-estate requirements and part count by more than half, while slashing development costs and time-to-market. Enpirion's patented approach capitalizes on semiconductor geometry advances that enable a 10x switching-frequency improvement, integrating a PWM controller, output FETs and magnetic components into a single turnkey IC package with a standard TSSOP footprint.
"With the increase in the number of voltages required on a single board, the space savings, ease of use and low profile of Enpirion's device offers design engineers a very compelling POL solution," said Vishal Sapru, research analyst with Power Supplies and Batteries practice at Frost &
"Enpirion's power converter, by virtue of its design, effectively addresses the key challenges faced by the power management industry which includes increased integration leading to reduced form factor and efficient thermal management. Its desirable board space savings feature will be a potent influencing factor for its adoption in various applications as occupation of significant space has been an inherent disadvantage for power management ICs," notes Deepa Doraiswamy, Research Analyst with Semiconductor practice at Frost & Sullivan.
The EN5330 is in a Dual Flat No-lead (DFN) TSSOP footprint package that covers just over 100sq. mm of board space. Including the minimum of three external components, the entire DC-to-DC converter can be placed in as little as 135sq. mm of single-sided, or 102sq. mm of double-sided board space. Combined with a height profile of 2.2mm and efficiencies up to 90%, the EN5330 is the perfect POL power solution for applications with even the smallest space requirements.
"Very high switching frequencies enable us to offer a DC-to-DC converter that is truly a complete Power System on a Chip," said Dr. Ashraf Lotfi, CTO of Enpirion. "These frequencies significantly reduce the amount of input and output capacitance required while at the same time offering an order of magnitude improvement on transient response."
Operation from common voltage rails of 2.5V, 3.3V and 5V is achieved with a wide input voltage range from 2.375V to 6.5V. With up to 3A or 10W of output power, the output voltage is VID pin selectable with options for seven standard voltages (0.8V to 3.3V) and a resistor divider setting enabling a continuous set-point range from 0.8V to Vin. The EN5330 can be used in a sequenced start-up with a programmable soft-start time and a separate enable function. Full protection functionality is offered with over-current, short-circuit, over-voltage, under-voltage and thermal shutdown features.
"A number of OEMs have indicated to us that the power section takes up a third or in some cases up to 75% of their board space," said Mark Downing, CEO of Enpirion. "With the Enpirion iPOWERTM POL solution and the inherent space savings, those OEMs can potentially reduce that fraction by 50% to 60%, directly contributing to a reduction in the overall system cost. This significant reduction in board space requirements, coupled with the reduction in development time and product cost, enables our customers to have a faster time to market and to be more competitive in their markets."
