Surface-mount convertor packs in 20W/cm3
Taiyo Yuden is claiming a world's first with its surface-mountable Micro DC/DC convertor.
Taiyo Yuden is claiming a world's first with its surface-mountable Micro DC/DC convertor Under low power output conditions, the novel new Micro DC/DC convertor functions together with the portable or other handheld device's battery to provide a distributed power source that minimises power loss through supply voltage control of the unit's RF power amplifier circuit

Smaller microfarad microlayers
Taiyo Yuden has announced a breakthrough in its MK series to include a new 1uF multilayer chip capacitor in an ultra small 0402 size and Y5V temperature coefficient.
Multilayer NTC chip thermistors
Taiyo Yuden's new high reliability multilayer NTC chip thermistors are 63mW devices in chip sizes of 0402 and 0603 with values from 47 to 150k Ohm.
The Micro DC/DC's exceptionally high power output per unit volume (20W/cm3) operates so efficiently (up to 85%) that the cellphone, PDA, DSC or other portable/hand held device actually conserves energy.
In the case of a cellular telephone this translates to an increase in talk time from 180 to as long as 250min: equating to a 39% improvement.
The chip accepts input voltages between 3.0 and 5.5V and provides an adjustable output from 0.8 to 3.0V DC at 350mA, with a typical output ripple of only 20mV peak-peak.
Production quantities of buck convertors are available now.
Engineering samples of four other device configurations - boost 1, boost 2, buck boost and inverting - are available now, and will be in full production in 2002.
The device's ultracompact package typically measures only 5.7 x 4.2 x 2.35mm.
Taiyo Yuden's advanced materials science and semiconductor mounting technology incorporate precise flip chip bonding with micron level control to achieve extremely small physical packaging, precise high-density component mounting and compatibility with standard tape-and-reel dispensers.
Taiyo Yuden's product roadmap for the micro DC/DC product calls for continued significant miniaturisation.
Next-generation Micro DC/DC convertors will offer up to a 500% increase in power-to-size ratio (100W/cm3) by the third quarter of 2002.
An intermediate stage, to be announced in April 2002, will double the power output by volume of today's component to 40W/cm3.
