Micrel Simplifies Point-of-Load Power Designs With New SuperSwitcher II High Power Density Synchronous Buck DC-DC Converter Family

“Coupled with a high level of integration in a small form factor, the SuperSwitcher IITM family delivers uncompromising performance, reduces cycle time, size and costs,” noted Andrew Cowell, vice president, analog marketing for Micrel.

“Leveraging our proprietary Hyper Speed Control architecture and innovative packaging, these devices are characterized with very low rdson, to deliver increased efficiency and thermal performance over the entire load,” noted Doyle Slack, senior marketing director for analog power, Micrel. “Micrel’s SuperSwitcher IITM family allows easy migration into applications where increased current levels or improved thermal performance is required.”

The SuperSwitcher IITM family of buck regulators are capable of driving DC-DC loads at more than 95 percent efficiency with ±1 percent accuracy, with output adjustable down to 0.8V. Micrel’s proprietary Hyper Speed ControlTM control architecture allows for ultra fast transient response requiring significantly lower output capacitance. These devices operate at a switching frequency of 300kHz and deliver very high efficiency across the DC load spectrum. The SuperSwitcher IITM family features an enable pin for very low power shutdown, internal soft start, undervoltage lockout, internal compensation and a host of protection features such as prebias safe startup, over temperature protection, foldback current limit and short circuit protection. The MIC26400, MIC26600 and the MIC26950 buck regulators are available in a thermally enhanced lead free 28-Lead 5mm x 6mm MLF® package.
