NXP Semiconductors N.V. unveils a generation of GreenChip power solutions, which the company claims to feature the lowest standby capability in the industry, reaching levels below 10mW. The NXP GreenChip power ICs, also known as Switch Mode Power Supply controller ICs, are designed for adapters for mobile devices such as cellphone chargers, tablets and notebooks, as well as major home appliances or white goods.

The GreenChip TEA1721 is the first member of the new high-performance low-power supply controllers with less than 10mW standby power consumption, optimized for use in mobile phone chargers and major home appliances. The GreenChip TEA173x, TEA1753 and TEA1703 ICs claim to deliver extremely low standby power for computing devices such as notebooks, tablets and netbooks, as well as printer adapters. Together, the devices are designed to meet tomorrow's intelligent power demands from standby to maximum output power, with the lowest standby power capability in the industry.

GreenChip TEA172x for the mobile phone chargers and major home appliances: NXP has developed the GreenChip TEA172x family of power supply ICs for products that have power requirements below 20W. Complete with the latest feature set and smart power control modes, the GreenChip TEA1721 is designed to help manufacturers develop cost-effective, intelligent devices.

The GreenChip TEA1721 is an AC/DC controller targeting up to 5W power supplies with ultra-low standby power consumption of less than 10mW. It contains a USB-compliant power supply controller with integrated MOSFET and a minimal number of external components. In addition, the device is compliant to the USB 1.1 and 1.2 charging specification.

GreenChip TEA173x, TEA1753 and TEA1703 for next-generation power supplies for computing: PCs, tablets, netbooks, computing peripherals and communications commodity applications all demand efficient power supplies with less standby power loss. For medium power levels, NXP now offers the GreenChip TEA173x and TEA1703, which are designed for applications that require an efficient and cost-effective power supply solution of up to 75W. Both come with a feature set and smart power management modes that resemble more advanced systems such as highly efficient notebook adapters, but at less cost. The GreenChip TEA173x family of AC/DC flyback controllers enables 90-percent efficient power supplies with less than 100mW of standby power using a minimal number of external components. By combining the TEA173x and TEA1703, manufacturers can create slim, compact designs and achieve standby power levels of even less than 10mW. The ICs combine fixed-frequency operation at high output power with frequency reduction at low output power, resulting in high-efficiency over the total load range.

For higher power levels, NXP provides the TEA1753, which features a flyback controller with integrated PFC controller. The TEA1753 is the latest derivative of the GreenChip III family, which works together seamlessly with the TEA1703 standby controller. While standby performance of the existing GreenChip III family was already lower than the 300mW industry standard, the addition of the TEA1703 will contribute a massive improvement to less than 30mW performance.

The GreenChip TEA1753, TEA1738, TEA1733 and TEA1703 are available now and are in volume production. Pricing for 1,000 pieces is $0.98 for TEA1753, $0.35 for TEA1738 and $0.38 for TEA1703. Samples of the GreenChip TEA1721 are also currently available, with volume production starting in Q2 2011; pricing is available upon request.
