11. Application information
A power supply with the TEA1752(L)T consists of a power factor correction circuit
followed by a flyback converter (See Figure 18 ).
Capacitor C VCC buffers the IC supply voltage, which is powered via the high voltage
rectified mains supply during start-up and via the auxiliary winding of the flyback converter
during operation. Sense resistors R SENSE1 and R SENSE2 convert the current through
MOSFETs S1 and S2 into a voltage on pins PFCSENSE and FBSENSE. The values of
R SENSE1 and R SENSE2 define the maximum primary peak current on MOSFETs S1 and S2.
In the example shown in Figure 18 , the LATCH pin is connected to a Negative
Temperature Coefficient (NTC) resistor. When the resistance drops below
V prot ( LATCH )
I O ( LATCH )
connected to the FBCTRL pin. Time-out protection is activated typically after 10 ms for a
120 nF capacitor. R LOOP is added so the time-out capacitor does not interfere with the
normal regulation loop.
R S1 and R S2 prevent the soft start capacitors from being charged during normal operation
due to negative voltage spikes across the sense resistors.
Resistor R AUX1 protects the IC from damage during events such as lightning strikes.
