Micrel Introduces New 18V, 3A, High Performance DC-DC Converter in 3mm x 3mm Footprint

SAN JOSE, CA--(Marketwired - Oct 23, 2013) - Micrel, Inc. (NASDAQ: MCRL), an industry leader in high performance linear and power solutions, LAN and timing and communications solutions, today introduced the MIC24085x family, a fixed frequency, current-mode DC-DC converter with integrated power MOSFETs. The MIC24085x is optimized for +12V rails and provides a flexible and cost-effective solution for distributed power systems and communication applications. The MIC24085A provides an adjustable output voltage from 0.9V to 5.5V; the MIC24085B/C/D/E/F provide fixed output voltages at 1.5V, 1.8V, 2.5V, 3.3V and 5V respectively. The MIC24085A-F are available in volume quantity with 1,000 quantity pricing starting at $0.53. Samples can be ordered on line at:

"Power supply designers face the challenge in finding an efficient, flexible and cost-effective solution that addresses the need for higher power density in the smallest possible real estate," noted Brian Hedayati, vice president of marketing for high performance linear and power solutions at Micrel. "Micrel's MIC24085 family will meet this challenge by offering an integrated 3A solution with nearly a 26 percent reduction in footprint compared to solutions currently on the market. The MIC24085x also achieves over 90 percent peak efficiency and consumes less than 10µA of supply current in shutdown mode."

The MIC24085 family of devices operates with an input voltage range of 4.5V to 18V and delivers 3A of output current while operating at a fixed frequency of 1MHz. Peak current mode architecture is used to provide fast transient response. At light load, the pulse frequency modulation (PFM) mode is used to boost overall efficiency.

The MIC24085 family improves system reliability by offering multiple protection features. These features include under-voltage lockout, internal soft start, cycle-by-cycle current limit, output overvoltage protection and thermal shutdown. Other features include an enable input and a PG (Power Good) output. The MIC24085 family is available in a 16-pin 3mm x 3mm MLF package with a junction operating range from -40degC to +125degC.
