Hello!
I am looking for a circuit that can boost the voltage of 1 V to approximately 5V and give me as an output current something like 250 mA. The whole idea is that I want to use solar cells to power a line following robot. I will not use any battery. Given that solar cells have little voltage and a lot of current then I thought of using a Boost Converter (circuit with timer circuit 555 or with LTC 3429 )to give me a voltage that I need. Now I can get 5.5 v but my output voltage will be 5 mA which is not enough to drive the robot forward. I am not that much sure about the load resistor (the will be DC Motor Dagu DG02S-2M with 48:1 Gear, 3V - angular with double sided shaft). But I have tested with 1000 ohm.
I really appreciate any help. Thanks a lot
