Description:
Universal mains supply operation (70 to 276 V AC)
High level of integration; giving a low external component count.
TEA1506T GreenChip II SMPS control IC 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.
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)
Short winding protection
Undervoltage protection (foldback during overload)
Overtemperature protection
Low and adjustable overcurrent protection trip level
Soft (re)start.
Application:
Besides typical application areas, i.e. TV and monitor supplies, the device can be used in adapters and chargers and all applications that demand an efficient and cost-effective solution up to 150 W. Unlike the other GreenChip II control ICs, the TEA1506 has no internal high voltage start-up source and needs to be started by means of an external bleeder resistor
Package included:
- 1 X TEA1506T GreenChip II SMPS control IC
