Product Summary

Universal mains supply operation (70 to 276 V AC)? High level of integration; giving a low externalcomponent count.Green features? Valley or zero voltage switching for minimum switchinglosses? Efficient quasi-resonant operation at high power levels? Frequency reduction at low power standby for improvedsystem efficiency (≤3W)? Cycle skipping mode at very low loads

Features

Safe restart mode for system fault conditions? Continuous mode protection by means ofdemagnetization detection (zero switch-on current)? Accurate and adjustable overvoltage protection (latchedin TEA1506; safe restart in TEA1506A)? Short winding protection? Undervoltage protection (foldback during overload)? Overtemperature protection? Low and adjustable overcurrent protection trip level? Soft (re)start
