Philips Presents New TEA1532 GreenChip IC

May 31, 2004 by Jeff Shepard

Royal Philips Electronics (the Netherlands) announced the expansion of its family of GreenChip 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 printers and other adapters, LCD monitors, set-top boxes, and DVD-recordable drives to reduce power consumption and increase efficiency in their applications.

The TEA1532 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. During CCM operation, it offers high power efficiency and low standby power levels. The TEA1532 also features a protection pin, brown-out protection and slope compensation. The TEA1532 features easy design capabilities, fewer external components and a high protection level.

Philips' TEA1532 offers over-temperature and over-voltage protection for safety, demagnetization detection, reduced power frequency during standby (less than 3 W), universal mains supply operation (from 70 Vac to 276 Vac), and the ability to be used for power ranges up to 250 W. The TEA1532 also offers maximum switching frequency set to 63 kHz and cycle skipping for low standby power levels. One additional feature is the built-in, high-voltage, startup 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.

The TEA1532 is available now for $0.50 each in quantities of 10,000.
