hello,
herewith i am attaching the scahmatic of pwm here i get the variable voltage from 0 to 5v but i am not getting my current requirment is the 100mA.so how to increase the current??
i would like if you provide me the information with schematic.
thanks.

You seem to be missing the attachment. In addition the question seems related to the previous thread you have created, is this a different problem?
 

Yes i applied the same thing but it want work in this circuit..
 

Hi,

read datasheet: is PIC capable of driving 100mA and keep an eye on the voltage.


increasing current:
* the simplest way is to just add a MOSFET or BJT.
* or complete halfbridge
* or driver IC...

it depens on what you need.
* min voltage, at max sink current
* max voltage at max source current
* frequency
* what load: completely resistive, capacitive, inductive
* min duty cycle
* max duty cycle

tell us a bit more...

Klaus
