Following characteristics are valid
-
for the full temperature range of Tambient = -40°C to +125°C,
-
a supply range of 32V
≥
vs > 6V
unless other conditions noted.
With 6V
≥
vs > vporh analogue parameters can not be guaranteed.
Note: The correct operation of the MLX10803 as a switching mode power supply for voltages lower than the
nominal supply voltage is dependent on the forward bias voltage of the used LED.
The user must ensure that at low supply voltage the peak current threshold voltage on the RSENSE pin can
be reached in order to keep the switching principle working.
If several pins are charged with transients above VS/PWM and below GND, the sum
of all substrate currents of the
influenced pins should not exceed 10mA for correct operation of the device.
Normal operating supply voltage is supposed to be 13.8V.
