Calculation of SG3524 PWM Recurrence and Obligation Cycle:

To work out the recurrence and obligation pattern of the PWM signal produced by the SG3524, we really want to consider the upsides of the outer parts associated with the IC.

Recurrence Calculation:
The recurrence of the PWM signal is determined by the upsides of the timing resistor (RT) and timing capacitor (CT) associated with the SG3524. The recipe to compute the recurrence is as per the following:

Recurrence = 1/(0.693 * CT * RT)

Where CT is in Farads and RT is in Ohms.

Obligation Cycle Calculation:


The obligation cycle addresses the level of time the PWM signal is in its high state contrasted with the all-out period. The obligation cycle is determined by the upsides of the timing resistor (RT), timing capacitor (CT), and input resistor (RF). The recipe to work out the obligation cycle is as per the following:

Obligation Cycle = (RF * RT)/(CT * (RF + R2))

Where RT, CT, RF, and R2 are in Ohms.

Model Calculation:

How about we accept we have the following part esteems:
RT = 10 kω
CT = 1 nF
RF = 10 kω
R2 = 10 kω

Recurrence Calculation:
Recurrence = 1/(0.693 * 1e-9 * 10e3)
≈ 14.4 kHz

Obligation Cycle Calculation:
Obligation Cycle = (10e3 * 10e3)/(1e-9 * (10e3 + 10e3))
= half

In this model, the PWM signal created by the SG3524 will have a recurrence of roughly 14.4 kHz and an obligation pattern of the half.
