Peak current definition
The peak current rating is a design parameter whose
value is dependent upon the overall application. For
the high brightness reference designs, a peak current
Once I PK is decided the value of R SENSE can be
determined by:
of 190mA was chosen to ensure that the converter
could provide the required output power to the LED.
In general, the I PK value must be chosen to ensure that
R SENSE =
V ISENSE
I PK
the switching transistor, Q1, is in full saturation with
maximum output power conditions, assuming
worse-case input voltage and transistor gain under all
operating temperature extremes.
A selection guide of sense resistor and inductor values
for given input voltages, output currents and number
of LED connected in series is provided in the table
below.
