Fujitsu today announced a new two-channel DC/DC converter IC with fast transient response, for use in digital consumer products, such as LCD TVs and digital video recorders. This new DC/DC converter IC, the MB39A145, utilizes a “bottom detection comparator method”, and includes new enhanced circuits which provide changes in voltage, for changes in current to realize a more stable and low ripple output voltage. The IC also includes Pulse Frequency Modulation (PFM)(2) that is highly efficient in low-current ranges, and allows the equipment to have low power consumption in stand-by mode. Samples of the new converter IC will be available from January 2010.
This Fast-Response DC/DC Converter IC for Consumer Electronics was jointly developed by Fujitsu Microelectronics and Fujitsu VLSI Limited, and will be exhibited at Embedded Technology 2009 to be held in Yokohama, Japan, from November 18-20
