3 - Dynamic output template
An external device is controlling the battery charge by means of a switch S1, which can be switched on and
off.
Following templates shows the output current and voltage during transients, this feature is very important to
enable the charging control by controlling S1 (PWM).
4 - Reverse current (main off)
Main off or unplug, the current flowing from the battery to the charger have to stay smaller than « Ir » in order
to prevent discharge !
Ir < 100µA for VBAT ≤ 5V
3.13.9.3 Thermal ratings
The heating of the enclosure will comply with EN 60950 § 5-1
Tab. 16 - part 2.
Thermal tests will be done with 230V +10%, the duration of the tests will be at least 3 hours stabilisation ,
the test circuit will be conform to paragraph 4.4 with K1 closed .
Bobbin temperature elevation have to be lower than 75°C in all cases , to insure a final temperature lower
than 115°C for 40°C ambient temperature .
Primary resistance increase with temperature and ∆θ = ∆R
