NXP Semiconductors today announced the launch of GreenChip TEA1733 - a low-cost IC that increases energy efficiency and standby performance of power supplies under 75W. Designed specifically for low-power computing and communication applications such as netbook adapters, printer adapter and LCD monitor supplies, the TEA1733 is a Switched Mode Power Supply (SMPS) controller IC that enables standby power levels less than 100mW. The GreenChip TEA1733 is the first of a complete series of low-power AC/DC control ICs to be launched by NXP over the next year.

“With the demand for sleek, light and compact designs increasing by the day, the TEA1733 enables consumers to experience lighter and more compact netbook adapters that save money and consume less power,” said Edwin Kluter, marketing director, power solutions, NXP Semiconductors. “The GreenChip TEA1733 enables new levels of energy efficiency in low-power applications. By reducing the number of external components needed, the TEA1733 allows OEMs to become more cost competitive while maintaining a high degree of quality and reliability.”

To enable higher efficiencies at low standby mode and at all load levels, the TEA1733 requires a very low start-up current of 10µA and consumes a low supply current of 1.25mA. The combination of fixed frequency operation at high output power and frequency reduction at low output power provides high efficiency over the total load range. Due to its high level of integration, the TEA1733 enables a compact and lighter power supply design with reduced number of external components in the SMPS.

The TEA1733 is available in a safe restart protection version as TEA1733 and also in a latched protection version as TEA1733(L).

With almost 500 million GreenChips already sold, NXP Semiconductors is at the forefront of designing and manufacturing energy efficient solutions for the power supply industry. The GreenChip family makes it easier and more cost-effective for power supply manufacturers to comply with energy efficiency specifications such as 80PLUS® and ENERGY STAR®. The GreenChip family of ICs is designed specifically for energy saving and has, from its inception, led industry standards in PC power efficiency especially in notebook power efficiency.
