Description
The Quasi-Resonant CoolSET™- (ICE5QRxxxxAx) is the 5th
generation of Quasi-Resonant integrated power IC optimized for
off-line switch power supply in cascode configuration. It is housed
in single package with 2 separate chips; one is controller chip and
other is HV MOSFET chips. The IC can achieve lower EMI and
higher efficiency with improved digital frequency reduction
through the proprietary novel Quasi-Resonant operation. The
enhanced Active Burst Mode enables flexibility in standby power
range selection. The product has a wide operation range (10 ~
25.5 V) of IC power supply and lower power consumption. The
numerous protection functions including the robust line
protection (both input OVP and brownout) to support the
protections of the power supply system in failure situations. All of
these make the CoolSET™ (ICE5QRxxxxAx) series an outstanding
integrated power device in Quasi-Resonant flyback converter in
the market.
