Philips Rolls Out GreenChip IC for Adapter Applications

6/11/2004 - Royal Philips Electronics (NYSE: PHG, AEX: PHI) announced the expansion of its industry-leading family of energy-efficient GreenChipTM power ICs with the introduction of a highly-integrated off-line flyback control IC, the TEA1532. Featuring multiple modes of operation, the chip enables manufacturers of systems such as printers and other adapters, LCD monitors, set-top boxes, and DVD recordable drives to reduce power consumption and increase efficiency in their applications.

With the proliferation of power-intensive devices in the home, there is a need for more energy-efficient solutions to lower power costs for the consumer and help sustain a greener environment. Philips’ GreenChip family meets these needs with a range of solutions to enable efficient power usage in today’s consumer electronic devices, both in standby mode and while in use.

“The customer demand for Philips’ GreenChip ICs is huge,” said Edwin Kluter, marketing manager, Integrated Power, Philips Semiconductors, Nijmegen. “This underscores the market acceptance for these products and their qualities. As of today Philips has sold more than 100 million GreenChip ICs worldwide that are being used in all kinds of applications, ranging from TV power supplies to notebook adapters.”

Meeting customer demand for more integrated, cost-effective power solutions, the TEA1532 is unique in that it combines both QR and CCM modes of operation into one IC with a footprint of SO8 and DIP8. During QR mode operation, the TEA1532 offers true valley switching, resulting in improved EMI performance. During CCM operation, it offers the highest power efficiency possible and low standby power levels. Like its GreenChip IC predecessors, the TEA1532 also features a versatile protection pin, brown-out protection and slope compensation, preventing sub-harmonic oscillation in CCM operation. The TEA1532 features easy design capabilities, fewer external components and a high protection level.

Philips’ TEA1532 offers all of the advantages of the rest of the GreenChip family, including over-temperature and over-voltage protection for safety, demagnetization detection, reduced power frequency during standby (less than 3W), universal mains supply operation (from 70 to 276V AC), and the ability to be used for power ranges up to 250W. The TEA1532 also offers maximum switching frequency set to 63kHz and cycle skipping for low standby power levels. One additional feature is the built-in High Voltage start-up current source that provides current when needed and which is switched off during normal operation. With this function, the current level is independent of the input voltage.

Philips’ TEA1532 is available now.

Philips Semiconductors’ eco-design policy states that products can only be termed “green products” if they offer one or more of the following: lower energy consumption, use of fewer environmentally hazardous materials, use of fewer overall materials, increased ease of recycling and disposal, or use of less packaging.
