Gen2 Voltage Regulators Set Efficiency Benchmark

Now in its second generation, the Gen2.1 SupIRBuck family of voltage regulators handle input voltages from 1.5V to 16V and deliver output voltages from 0.7V to 90% of the input voltage with a peak efficiency greater than 96%. Providing up to 12A of output current in 5 mm x 6 mm Power QFN packages, programmable switching frequencies range up to 1.5 MHz. The devices also eliminate the need for traditional dual-stage POL conversion by operating directly from 12V. Additional features include a 1% accurate 0.7V reference voltage, programmable hiccup current limit, programmable soft start, enhanced pre-bias start up, thermal protection, an enable pin with voltage-monitoring capability, sequencing (IR384xW), DDR memory tracking (IR383xW), and an operating temperature range from -40°C to +125°C. Prices range from $1.38 to $2.31 each/1,000. For more information, contact Sian Cummins at INTERNATIONAL RECTIFIER, El Segundo, CA. (310) 252-7148.
