Re: help!!IC UC3524
Hi Hari, the spec. r below or u can refer to this for more detail
under liquidgear
The circuit should be designed to obtain a frequency of 3.5KHz.
SPECIFICATIONS:
•Power supply to the circuit = 10V DC.
•The output of the circuit should be PWM (Pulse width modulated) waveform.
•The chopper frequency = 4kHz ±15%.
•The duty cycle should be manually variable from 0 to 100%.
•There circuit should have emergent stop function.
•The block diagram of the circuit is shown in Figure 1.
•The PWM waveform is shown in Figure 2.
DESIGN CONSIDERATIONS:
•The circuit should be designed using UC3524 to obtain the specified frequency and variable duty cycle.
•A MOSFET is used as the switch as shown in Figure 1 and the waveform as in Figure 2.
•After successful testing on resistive load, the circuit is then used to drive a DC motor and realize variable speed control.
Pls sent me the schematic diagram thank.
