hi, all
in dc/dc converter, such as boost, usually have input voltage from 2.7v to 4.2v, and the output is 5v, so the duty cycle can calculate, one is 0.46(2.7v) the other is 0.16(4.2v), does it means this boost can work normal with 0.16<=D<=0.46?
now i have question:
1. which part confirm the duty cycle range? the error opamp output range?
2. now if i have input voltage is 2v, i also want the output voltage is 5v, how to do?
thanks.
