However, if required this pinout can be configured with an external transistor which can ground this pin during a critical situation, enabling a shutdown of the IC output. Mostly this pinout is connected to ground via a RC network. Pin#9 (Compensation): This pinout is for compensating the error amplifier op amp. The capacitor connected across this pin and ground decides the level of soft initialization of the output of the IC. Pin#8 (Soft Start): This pinout as the name suggests is used for initiating the operations of the IC softly instead of a sudden or an abrupt start. A resistor connected across this pin#7 and pin#5 fixes the dead time of the IC. Pin#7 (discharge): This pinout can be used for determining the deadtime of the IC, meaning the time gap between the switching of the two outputs of the IC (A and B).

RD = Deadtime resistor connected between pin#5 and pin#7 (in Ohms).

RT = Timing Resistor at pin#6 (in Ohms).

CT = Timing Capacitor at pin#5 (in Farads).

The formula for calculating the frequency of IC SG3525 with respect to RT and CT is given below: Ct must beВ attachedВ with a calculated capacitor while the Rt pin with a resistor for optimizing the frequency of the IC. Basically these pinouts are connected with an external resistor and a capacitor for setting up theВ frequencyВ of the inbuilt oscillator stage or circuit.

Pin#5 and #6В (Ct, Rt): These are termed CT, RT respectively. Out): It's the oscillator output of the IC, the frequency of the IC may be confirmed at this pin out. This is generally done when more than a single IC is used and requires to be controlled with a common oscillator frequency. Pin#3 (Sync): This pinout can be used for synchronizing the IC with an external oscillator frequency. This will prompt the IC to take necessary corrective measures by adjusting the output PWM, so that the voltage is restricted to the normal level. Now, if the output voltage tends to increase above this set limit, the feedback voltage would also increase proportionately and at some point exceed the reference limit. The feedback voltage should be adjusted to be just below the internal reference voltage value (5.1 V) when the output is normal. It is usually done by applying a feedback voltage from the output through a voltage divider network to the non-inverting input of the op amp (pin#1). Thus these EA pins 1 and 2 can beВ effectivelyВ configured for implementing an automatic the output voltage correction of a converter. It's a simple op amp arrangement inside the IC which controls the PWM of the IC outputs at Pin#11 and Pin#14. Pin#1 is the inverting input while pin#2 is the complementary non-inverting input. Pin#1 and #2 (EA inputs): These are inputs of the built-in error amplifier of the IC.
