to D6, which is necessary to prevent latch-up of the
LT1474’s output switch if the voltage at its SW pin is
held up while V IN drops. This situation may easily
The addition of R3 will slightly affect the actual center
voltage; however, this change will typically not be
significant in comparison with the size of the hysteresis
band. For a typical V c (>3.3V), the final value of V c will
be lowered. As indicated by Figure 5, however, driving
the piezo to moderately higher open-circuit voltages
than optimal does not have an excessive impact on
efficiency.
Check: Actual V h and V l
Once all resistor values are chosen, the actual upper
and lower trip points will be defined by:
occur in an application where the load is powered by
multiple sources or includes a storage element, such
as supercapacitor or battery, whose voltage drops
more slowly than that of C1 when no harvested power
is available. The user must then choose D6 so that the
voltage at SW cannot exceed the voltage at V IN by the
0.6V required for latch-up. Particularly at high C1
voltages, the designer must also take steps to ensure
that reverse leakage over D6 will not allow the voltages
at the V FB and SW pins to float above their maximum
ratings at no load.
