TEA1713T Description
The TEA1713 integrates a Power Factor Corrector (PFC) controller and a controller for a Half-Bridge resonant Converter (HBC) in a multi-chip IC. It provides the drive function for the discrete MOSFET in an up-converter and for the two discrete power MOSFETs in a resonant half-bridge configuration. The efficient operation of the PFC is achieved by implementing functions such as quasi-resonant operation at high power...
TEA1713T Key Features
- Integrated PFC and HBC controllers
- Universal mains supply operation (70 V to 276 V (AC))
- High level of integration resulting in a low external ponent count and a cost effective design
- Enable input (enable only PFC or both PFC and HBC controllers)
- On-chip high-voltage start-up source
- Stand-alone operation or IC supplied from external DC source
- Boundary mode operation with on-time control Valley/zero voltage switching for minimum switching losses Frequency limiti
- Integrated high-voltage level shifter Adjustable minimum and maximum frequency Maximum 500 kHz half-bridge switching fre
- Safe restart mode for system fault conditions
- General latched protection input for output overvoltage protection or external temperature protection
