Preliminary specification
GreenChip™II 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/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) Burst mode operation for very low standby levels (<1 W) 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 Short winding protection Undervoltage protection (foldback during overload) Overtemperature protection Low and adjustable overcurrent protection trip level Soft (re)start Mains voltage-dependent operation-enabling level. APPLICATIONS Besides typical application areas, i.e. TV and Monitor supplies, the device can be used in all applications that demand an efficient and cost-effective solution up to 250 W.
