I'm designing a circuit based on the MC34063A switching regulator to step up 3.7V to 8V.
The 3.7V for Vin comes from a 3.7V Li Ion battery and so I'm trying to calculate the battery life. I'm a bit confused on some of the parameters from the datasheet though. It states that Icc (supply current) is typically 2.5mA. This seems a bit too low to use as a value for the total current consumption. However, I've calculated that Ipk for my application (8V @ 200mA) will be around 1A. I know it's a switching regulator though and so the the waveform for the Ipk value looks more like a triangular waveform. Would an average of Ipk give a better indication of power consumption?
I'm just wondering if anyone would point me in the right direction with regards to calculating total power consumption so that I can calculate my battery life.
