TEA1506AT Description
is the second generation of green The Switched Mode Power Supply (SMPS) control ICs. A high level of integration leads to a cost effective power supply with a low number of external ponents. (1) GreenChip is a trademark of Koninklijke Philips Electronics N.V.
TEA1506AT Key Features
- Universal mains supply operation (70 to 276 V AC)
- High level of integration; giving a low external ponent 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. 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 TEA1506; safe restart in TEA1506A)
