- MIC2205 IC Features Ultra-Low Noise, Extended Battery Life
Micrel Inc., (Nasdaq: MCRL), an industry leader in Power, Connect and Protect IC solutions, today announced the MIC2205, a new high frequency, small size dc/dc step-down regulator featuring an ultra-low noise and ultra-low quiescent current standby mode. The device provides the ideal solution for designers of portable systems such as cell phones, PDAs, and digital cameras. The MIC2205 is currently sampling with volume quantities available within 10-12 weeks. Pricing starts at US$1.61 in 1K quantity.
"The MIC2205 addresses three major concerns of portable electronics designers: noise, battery life and size," said Tony O''Brien, Micrel''s director of marketing, power products. "The chip features up to 100 times less output noise than other solutions, provides a low quiescent current mode of operation to maximize battery life, and comes in a tiny, 3mm x 3mm MLF(TM) package thus saving valuable board space."
The chip offers two modes of operation: low quiescent current (18uA) LOWQ(TM) standby mode and high output current PWM mode. The output noise in standby mode is just 75uV versus other solutions at 100mV. The MIC2205 is high-current-capable (600mA) in PWM mode and can provide efficiencies up to 95 percent. In addition, the MIC2205 saves valuable board space with its very small packaging and a 2.2uF ceramic output capacitor that is up to ten times smaller than other solutions.
"Micrel never forgets that one of our primary customers is the design engineer who continues to be concerned with increasing functionality for products in the growing mobile phone market," noted Bob Whelton, executive vice president operations, Micrel. "The MIC2205 avoids the pitfalls of noisy light-load switching regulators with a simple integrated solution -- an important consideration for mobile phone designers who must also be mindful of overall system costs."
