Description
The Quasi-Resonant CoolSET™- (ICE5QRxx80BG) is the 5
th
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™ (ICE5QRxx80BG) series an outstanding
integrated power device in Quasi-Resonant flyback converter in
the market.
Robust line protection with input OVP and brownout
Auto restart mode protection for VCC Over Voltage, VCC Under
Voltage, Over load/Open Loop, Line/Output Over Voltage, Over
Temperature
Limited charging current for VCC short to GND
Pb-free lead plating, halogen free mold compound, RoHS
compliant

Feedback & Burst entry/exit control
FB
pin combines the functions of feedback control, selectable burst entry/exit
control and overload/open loop protection.
Input Line OVP & Brownout
VIN
pin is connected to the bus via resistor divider (see Figure 1) to sense the
line voltage. This pin combines the functions of input Line OVP, Brownout and
minimum ZC count setting for low and high line.
Current Sense
The
CS
pin is connected to the shunt resistor for the primary current sensing
externally and to the PWM signal generator block for switch-off determination
(together with the feedback voltage) internally.
Zero Crossing Detection
ZCD
pin combines the functions of start up, zero crossing detection and output
over voltage protection. During the start up, it is used to provide a voltage level
to the gate of power switch CoolMOS™ to charge V
CC
capacitor.
Drain
The
DRAIN
pin is connected to the drain of the integrated CoolMOS™.
VCC(Positive Voltage Supply)
The
VCC
pin is the positive voltage supply to the IC. The operating range is
between V
VCC_OFF
and V
VCC_OVP
.
Ground
The
GND
pin is the common ground of the CoolSET™.
