Convertor chips boost battery life
Designers of portable high-performance applications with low-power requirements can increase system run-times and save board space using new 1.2A synchronous step-down DC/DC convertors.
Designers of portable high-performance applications with low-power requirements can increase system run-times and save board space by using new 1.2A synchronous step-down DC/DC convertors from Texas Instruments TI's TPS6204x family of step-down convertors enables an extremely low quiescent current of 18uA and 95% conversion efficiency to conserve battery life in one-cell lithium-ion (Li-ion) or three-cell nickel-metal-hydride (NiMH) and nickel-cadmium (NiCd) powered applications such as wireless PDAs, smartphones, notebooks and broadband equipment

Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
The convertors reduce board space by integrating all necessary switching transistors and operating at a fixed frequency of 1.25MHz to help minimise inductor size.
In addition, the devices are available in small 3 x 5mm, 10-pin micro-small outline packages (MSOPs), allowing designers to reduce both board space and system cost.
The TPS6204x series manages input voltages from 2.5 to 6V and supply output voltages as low as 0.7V, ideally suited to supply the ultra-low core voltage of today's low-power processors such as TI's TMS320C5000 DSP platform and other microprocessors.
Additional features include: adjustable and fixed voltage options; pulse frequency modulation (PFM)/pulsewidth modulation (PWM) mode for high efficiency over a wide load current range; 100% maximum duty cycle for lowest dropout; low-noise operation in forced fixed frequency PWM operation mode; power save mode operation at light load current levels; and short-circuit detection.
The TPS6204x devices are available today in volume from TI and its authorised distributors.
Suggested pricing in quantities of 1000 is $2.09 per unit.
