hello,
Iam designing a sinusoidal PWM inverter. I came to know about HEF4752 with this form.

http://www.datasheetcatalog.org/datasheet/philips/HEF4752VP.pdf

How can i vary the frequency of the output voltage?
What is FCT, RCT, VCT, OCT?

with regards..

 

Hello,

The signals are descibed in the datasheet :

How to use them is shown in fig 3 of the datasheet.

HI,
Ok i got that in the datasheet itself. But what is that frequency clock, voltage clock?
How can i vary the output frequency?
I dont need the manual control of frequency. It seems the 47k pot is used to vary the frequency. is it correct?
In my circuit, iam having a working voltage which decides the frequency output.
using that voltage i need to control the output frequency of this IC.
