DC/DC SoCs Reset Efficiency And Power Density Bars

June 8, 2010
EN6300 family of voltage mode synchronous buck dc/dc converters includes the 3A EN6337QI, 4A EN6347QI, 8A EN6360QI, and 12A EN63A0QI.

Said to raise efficiency and power density benchmarks, the EN6300 family of voltage mode synchronous buck dc/dc converters includes the 3A EN6337QI, 4A EN6347QI, 8A EN6360QI, and 12A EN63A0QI. They achieve efficiencies up to 96% and employ a chip architecture that enables a power density in the realm of 113W/square inch (17.6 W/cm2). They also trim parts counts by integrating the inductor, power switches, gate drive, controller, and loop compensation. Shared features include an input voltage from 2.375V to 6.6V, full load operation across a temperature range from -40°C to +85°C without the need for airflow or heat sink, and phase-locking for input clock synch to reduce input ripple and remove beat frequencies. Prices range from $2.71 to $10 each/1,000. ENPIRION INC., Hampton, NJ. (908) 894-6000.
