Note 1:
T
J
is calculated from the ambient temperature T
A
and power
dissipation P

according to the following formula:
LTC1435CG/LTC1435IG: T

Note 2:
The LTC1435 is tested in a feedback loop which servos V
OSENSE
to the balance point for the error amplifier (V
ITH
= 1.19V).
Note 3:
Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency. See Applications Information.
Note 4:
Oscillator frequency is tested by measuring the C
OSC
charge and
discharge currents and applying the formula:
