Application Notes
c Current Limiter for LED
Chip POSISTOR r : PRG series
1. Applications
POSISTOR r is an effective current limit solution based
on LED's allowable current and temperature
characteristics.
(1) LED lighting instruments
(2) LED backlight of flat displays
See below figures.

2. Benefits
(1) Higher LED brightness versus a fixed resistor. LED
can work in the smaller series resistance with
POSISTOR r at normal operation temperature. The
number of LEDs is possibly reduced.
(2) LED lifetime may be extended due to the current
limiting function of the POSISTOR r in cases of
overheat or overcurrent situation.
(3) Small 0805 package allows the POSISTOR r to be
placed close to the LED. It offers accurate detection of
ambient temperature near LED and increases
flexibility of packaging.
3. Recommended part numbers
Choose an appropriate part number having max. voltage
and resistance value. Review the protective threshold
current range based on the operating current and
temperature of the LED.
