TEA1733P
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)
The output power of the converter is regulated by the CTRL pin. 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. V ctrl(Ipeak) (see Figure 1 ) is set by the CTRL. 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 will continue switching.
