Video buffer promises 'green energy' features

To help makers design energy-efficient consumer electronics, Texas Instruments Inc. has launched a flexible four-channel video buffer that it claims uses 57 percent less power compared to its closest competitor.

The new device has a power-down design to reduce system power use even more and help the manufacturers to achieve Energy Star compliance in STBs and personal and digital video recorders. The balance of ultralow power and lower space and cost also makes the amplifier fit for video surveillance systems and SCART A/V connectors. Development tools help designers to easily configure and test the amplifier for SCART applications, minimizing the need for expensive components.

The THS7374 and THS7375 support a wide supply voltage ranges from 2.85V to 5.5V, providing makers with maximum flexibility while using minimal power. The devices have a 9.6mA total quiescent current at 3.3V supply for all four channels. Even operating at 5V, each device has 10mA total quiescent power. A power-down option further lowers quiescent current consumption to 0.1?A, making the THS7374/5 suitable choices for consumer device systems seeking Energy Star compliance.

The THS7374 and THS7375 are available now in a 14-pin TSSOP Pb-free (RoHS compatible) and green-compliant package.
