TEA1713T
Resonant power supply control IC with PFC
2. Features and benefits
2.1 General 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 component 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
2.2 PFC controller features
Boundary mode operation with on-time control
Valley/zero voltage switching for minimum switching losses
Frequency limiting to reduce switching losses
Accurate boost voltage regulation
Burst mode switching with soft start and soft stop
2.3 HBC controller features
Integrated high-voltage level shifter
Adjustable minimum and maximum frequency
Maximum 500 kHz half-bridge switching frequency
Adaptive non-overlap time
Burst mode switching
2.4 Protection features
Safe restart mode for system fault conditions
General latched protection input for output overvoltage protection or external
temperature protection
Protection timer for time-out and restart
Overtemperature protection
Soft (re)start for both controllers
Undervoltage protection for mains (brownout), boost, IC supply and output voltage
Overcurrent regulation and protection for both controllers
Accurate overvoltage protection for boost voltage
Capacitive mode protection for HBC controller
3. Applications
LCD television
Plasma television
Adapters
