Micrel Introduces Industry's First Triple 2Amp-per-Output Synchronous Buck Regulator

[By NBC-1TV H. J Yook]Micrel, Inc. (NASDAQ: MCRL), an industry leader in high-performance Linear and Power solutions, LAN and timing and communications solutions, today announced the MIC23450 and MIC23451, two triple-output, high-efficiency synchronous buck regulators designed with Micrel's HyperLight Load® technology. The MIC23450 delivers two Amps per output and the MIC23451 provides one Amp per output. Both regulators operate at 3MHz in PWM mode which allows the use of tiny, low-cost capacitors and inductors thereby creating one of the smallest, simplest to use triple-buck regulators in the industry. Users may program each of the three outputs independently to operate from 1.0V to 3.3Vusing external resistors. The MIC23450 /51 support an input voltage range of 2.7V to 5.5V making them both ideal for Li-ion/polymer or alkaline/NiCad/NiMH applications, as well as point-of -load (POL) DC-to-DC conversions; an area where maximizing power density and efficiency is paramount. The MIC23450 is currently available in volume with pricing starting at $1.28 for 1K quantities. The MIC23451 pricing starts at $1.32 for the same quantities. Samples can be ordered at: http://www.samplecomponents.com/scripts/samplecent...

“The MIC23450 and the MIC23451 both provide superior light-load efficiency which allows system designers to reduce the amount of power consumed during light-load conditions. This is an important requirement for battery powered applications,” noted Brian Hedayati, vice president of marketing for high-performance Linear and Power Solutions at Micrel. “Benefiting from Micrel‘s Hyperlight Load architecture, design engineers can now use a wide range of inductors and capacitors and be assured of stable operation without the need for any external compensation. In addition, the MIC23451 utilizes Micrel’s cutting-edge, copper-pillar package technology that significantly reduces size while enhancing thermal and electrical performance.”
