TEA1733CT
GreenChip SMPS control IC
The PROTECT input can be used to create overvoltage detection and OTP functions.
A small capacitor can be connected to the pin if the protections on this pin are not used.
An internal clamp of 4.1 V (typical) protects this pin from overvoltages.
7.6 Duty cycle control (CTRL pin)
Pin CTRL regulates the output power of the converter. This pin is connected to an internal
5.4 V supply using an internal 7 k ? resistor.
The CTRL pin voltage sets the peak current which is measured using the ISENSE pin
(see Section 7.10 ). At a low output power the switching frequency is also reduced (see
7.7 Slope compensation (CTRL pin)
A slope compensation circuit is integrated in the IC for CCM. Slope compensation
guarantees stable operation for duty cycles greater than 50 %.
7.8 Overpower timer (OPTIMER pin)
If the OPTIMER pin is connected to capacitor C4 (see Figure 3 ), a temporary overload
situation is allowed. Pin CTRL sets V ctrl(Ipeak) (see Figure 1 ). When V ctrl(Ipeak) is above
400 mV, the I IO(OPTIMER) current (11 ? A typical) is sourced from the OPTIMER pin. If the
voltage on the OPTIMER pin reaches the V prot(OPTIMER) voltage (2.5 V typical) the
OverPower Protection (OPP) is triggered (see Figure 5 ).

Overpower delay
When the V prot(OPTIMER) voltage is reached the device restarts. If the overload is removed
before the V prot(OPTIMER) voltage is reached, the converter continues switching.
