duration of the burst and T is the period of the transmit
burst rate (essentially the time between bursts).
In this example, I
T = one hour. The average charge current required from
the LTC3108 would be:
Therefore, if the LTC3108 has an input voltage that allows
it to supply a charge current greater than 5.14µA, the
application can support 100mA bursts lasting 5ms every

hour. It can be determined that the sleep current of 5µA
is the dominant factor because the transmit duty cycle is
so small (0.00014%). Note that for a V
average power required by this application is only 17µW
(not including converter losses).
Note that the charge current available from the LTC3108
has no effect on the sizing of the V
assumed that the load current during a burst is much larger
than the charge current), and the V
effect on the maximum allowed burst rate.
