... NXP Semiconductors 11. Application information A power supply with the TEA1733BT is a flyback converter operating in Continuous conduction mode (see Capacitor C5 buffers the IC supply voltage, which is powered via resistor R3 at start-up and via the auxiliary winding during normal operation. Sense resistor R9 converts the current through MOSFET S1 into a voltage on pin ISENSE. The value of R9 defines the maximum primary peak current on MOSFET S1 ...
