GreenChipTMII SMPS control IC
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 over
voltage protection (latched in TEA1533P, safe restart in TEA1533AP) Short winding protection Under
voltage 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
TEA1533P; TEA1533AP
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...
