2 / 24 page 2002 Aug 23 2 Philips Semiconductors Product specification GreenChipTMII SMPS control IC TEA1533P; TEA1533AP FEATURES Distinctive features • Universal mains supply operation (70 to 276 V AC) • High level of integration, giving a very low external component count. Green features • Valley or zero voltage switching for minimum switching losses • Efficient quasi-resonant operation at high power levels • Frequency reduction at low power standby for improved system efficiency (<3 W) • Cycle skipping mode at very low loads. Pi <300 mW at no-load operation for a typical adapter application • On-chip start-up current source. Protection features • Safe restart mode for system fault conditions • Continuous mode protection by means of demagnetization detection (zero switch-on current) • Accurate and adjustable overvoltage protection (latched in TEA1533P, safe restart in TEA1533AP) • Short winding protection • Undervoltage protection (foldback during overload) • Overtemperature protection (latched in TEA1533P, safe restart in TEA1533AP) • Low and adjustable overcurrent protection trip level • Soft (re)start • Mains voltage-dependent operation enabling level. APPLICATIONS Besides typical application areas, i.e. adapters and chargers, the device can be used in TV and monitor supplies and all applications that demand an efficient and cost-effective solution up to 250 W.
