Micrel Launches Industry's Smallest and Thinnest 8 MHz, 'Inductorless' Buck Regulator for Portable Power Applications
Electronica to Provide Sneak Peek at Micrel's MIC3385
SAN JOSE, Calif., Nov. 15 -- Micrel Inc., (NASDAQ:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today announced that it would be previewing the MIC3385, the industry's smallest and thinnest 8 MHz inductorless buck regulator at Electronica 2006 in Munich, Germany. Housed in a 3 x 3.5 x 0.9mm MLF package, the new device is ideal for ultra-thin mobile phones, PDAs, GPS systems, digital cameras, portable media players and portable gaming devices. The IC is currently sampling to select customers, with volume production expected by the end of 2006. Pricing will start at $1.75 for 1,000 part quantities.
"Earlier this year, Micrel broke the 8MHz barrier and now has an inductorless solution that gives designers of feature rich cell phones and portable products a groundbreaking reduction in solution footprint and solution height," noted Ralf Muenster, Micrel's director of marketing for power products. "The MIC3385 is a revolutionary development in buck regulators for portable applications, making the design of a switching regulator as simple as designing with a linear regulator"
With ripple performance below 8mV @500mA and efficiency up to 90 percent, the MIC3385 achieves best-in-class performance in all areas critical to mobile phones. The Micrel device also features a light load LDO mode with only 20µA of ground current. This light load mode not only improves efficiency in standby mode, but also improves transient performance, since the LDO assists the switching regulator during demanding load transients. This is critical in applications such as baseband and applications processors, which require tightly regulated voltages for error free operation.
The IC operates from 2.7V to 5.5V input and features internal power MOSFETs that can supply up to 500mA output current in PWM mode. It can also operate with a maximum duty cycle of 100 percent for use in low dropout conditions. The MIC3385 is qualified to the full industrial temperature range of -40 degrees C to +125 degrees C.
