Micrel Rolls Out Company’s Smallest 3A PWM Buck Regulator Solution

San Jose, Calif. - Micrel Inc. today launched the MIC2207, a 3 mm x 3 mm MLF™ 2MHz 3A PWM buck regulator. The chip, which offers the smallest footprint available on the market, is aimed at applications requiring up to 3A output from 5V and 3V rails. It is ideal for applications in the telecom/networking equipment, server and consumer electronics markets.

“The need for smaller footprint and higher power density continues to be a key consideration for designers across many applications and markets,” noted Ralf Muenster, Micrel’s Director of Marketing for Power Products. “Micrel’s MIC2207 buck regulator offers our customers a 33 percent reduction in board occupancy when compared to our competitors. In addition, the MIC2207 gives customers a very cost effective solution by eliminating or reducing the size of external components.”

The MIC2207 features an ultra-fast operation and a proprietary internal compensation which allows for extreme transient response and the usage of the smallest and one of the most cost-effective LC components in its class. A low resistance integrated p-channel MOSFET allows the chip to deliver up to 3A with more than 94 percent efficiency. The output voltage can be adjusted down to 1V and can operate with a maximum duty cycle of 100 percent for use in low dropout conditions. The P-MOSFET also eliminates the need for a sense resistor to provide a current limit, consequently further reducing the need for external components.
