... GreenChip SMPS control IC Rev. 6 — 15 February 2011 1. General description The TEA1733P is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. It operates in fixed frequency mode. To reduce ElectroMagnetic Interference (EMI), frequency jitter has been implemented. Slope compensation is integrated for Continuous Conduction Mode (CCM) operation. ...

... A restart caused by a protection rapidly charges the OPTIMER pin to 4.5 V (typical). The TEA1733P enters Power-down mode until the OPTIMER pin discharges down to 1.2 V (typical). In Power-down mode, the IC consumes a very low supply current (10 μA typical) and the VCC pin is clamped (typical internal clamp circuit ...

... The clamp voltage on the PROTECT pin is lowered when the power-down (latched or restart protection). 11. Application information A power supply with the TEA1733P 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 the MOSFET S1 into a voltage on pin ISENSE ...
