Note 4
: At an input supply less than 2.3V, only the start-up circuitry of the
LTC1700 is active. This test ensures the start-up circuitry is working.
Note 5:
An input supply at or above this minimum operating voltage
activates the main control loop. Start-up circuitry of the LTC1700 is
shut off.
Note 6:
Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
Note 7:
The LTC1700 is tested in a feedback loop that servos V
FB
to the
feedback point for the error amplifier (V

= 0.6V)
