IC forbedrer adapter-effektviteten

NXP’ har lanceret medlem af GreenChip familien, der kan bane vejen for en markant forbedring af effektiviteten i power adaptorer (in english). 

NXP Semiconductors announces GreenChip TEA1733(L) - 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, says 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).
