Introduction
The ICL5101 is a high-performance mixed-signal controller for LED and SMPS applications. The IC is designed
for a Power Factor Correction (PFC) close to 1, low THD below 5 %, a maximum efficiency up to 94 % PLUS
and a minimal design-in phase due to use resistors only for setting up the IC. The IC is designed to working in
ultra-wide and narrow range designs. Furthermore, all parameters are valid in an extended temperature range
from –40 °C up to 125 °C – especially frequency and timing. The controller utilizes a variety of protection
features, including saturation control during start-up of the resonant converter, external adjustable over
temperature, along with open and short load conditions. The ICL5101 includes also a surge protection feature,
provides together with the CoolMOS technology a maximum protection against surges and safe components on
board. Nevertheless CoolMOS P6 increases the efficiency by a 30% reduced gate charge and the internal gate
resistor improves an easy use. For the half bridge is also a 500V CE CoolMOS recommended.
