I am working on my project with BOOST CONVERTER and i am thinking of using 555 timer for the gating pulses,i just wanna know by how many ways by which i can change the duty cycle of 555(in astable mode)?
This is not exactly what you asked, but have a look at the MC34063 IC, it is a simple little 8-pin IC similar to a 555 timer, but designed to make buck and or boost converters with.I am working on my project with BOOST CONVERTER and i am thinking of using 555 timer for the gating pulses,i just wanna know by how many ways by which i can change the duty cycle of 555(in astable mode)?
A micro would probably be the cheapest solution for anyone doing this commercially.most importantly less costlier driver for solar street lights
First you said generating a linear ramp is inefficient... now you want to use it! Stop contradicting yourself!Thanks a lot for the replies,i am thinking of using two bjt astable multivibrator with current mirror circuit across the capacitor, thus generating a ramp signal which in turn can be using to generate variable duty cycle pwm signals using a comparator,but i need to know whether this will work!
