AN10907
TEA1613T resonant power supply control IC
2.3 Resonant half-bridge controller features
•
Integrated high-voltage level shifter
•
Adjustable minimum and maximum frequency
•
Maximum 500 kHz half-bridge switching frequency
•
Adaptive non-overlap timing
•
Burst mode switching
2.4 Protection features
•
Safe restart mode for system fault conditions
•
General latched protection input for output over-voltage protection or external
temperature protection
•
Protection timer for time-out and restart
•
Overtemperature protection
•
Soft (re)start
•
Under-voltage protection for boost (brownout), IC supply and output voltage
•
Over-current regulation and protection
•
Input voltage brownout
•
Capacitive mode protection for resonant converter
2.5 Protection
The TEA1613T provides several protection functions that combine detection with a
response to solve the problem. By regulating the frequency as a reaction to, for example,
over-power or bad half-bridge switching, the problem can be solved or operation kept safe
until it is decided to stop and restart (timer-function).
