SmartRectifier™ Solutions
for Synchronous Rectification
The IR Advantage:
• Simple, powerful solution
• Enables
– Higher efficiency
– Higher power density
– Faster time-to-market
• Complies with CEC 80plus and 0.3W
standby requirements
• Proprietary “Voltage Level Detection”
and 200V HVIC technology
• Direct connection and drive to all
30-200V MOSFETs
• Enables ‘no heatsink’ SR designs
Synchronous rectification is broadly used in AC/DC converters to replace Schottky diodes
and improve converter efficiency. IR’s SmartRectifier™ family offers simple high efficiency
secondary side synchronous rectification for all operating modes over a broad array of
topologies.
IR1163 is a smart secondary-side driver IC designed to drive N-Channel power MOSFETs
used as synchronous rectifiers in isolated Flyback, Forward, LLC, Half-bridge or full-bridge
converters. IR1163 works in both DCM and CCM operation modes. The SYNC pin is used
in CCM mode to directly turn-off the MOSFET by a control signal. IR1163 has wide Vcc
operating range from 5V to 20V. It has ultra-low sleep mode current, enables lower system
standby power.
The IR1169 is a smart secondary-side driver IC designed to drive N-Channel power
MOSFETs used as synchronous rectifiers in isolated Flyback, Forward, LLC or Half-bridge
converters. The IR1169 works in both DCM and CCM operation modes. The SYNC pin is
used in CCM mode to directly turn-off the MOSFET by a signal from secondary or primary
controller using simple capacitive coupling interface.
The IR1166(2) and IR1167(2) are smart secondary side driver ICs designed to drive N-Channel
power MOSFETs used as synchronous rectifiers in isolated Flyback and resonant halfbridge converters. These ICs can control one or more paralleled N-MOSFETs to emulate
the behavior of Schottky diode rectifiers.
The IR1168(2) is a dual smart secondary-side rectifier driver IC designed to drive two
N-Channel power MOSFETs used as synchronous rectifiers in resonant converter
applications. This IC offers shoot-through protection improving efficiency and increasing
system reliability. This IC can control one or more paralleled MOSFETs to emulate the
behavior of Schottky diode rectifiers.
Note: IR1163 will be released in July 2014
