ICE5BR3995CZ
65 kHz offline flyback regulator with integrated 950 V CoolMOS™ superjunction MOSFET and line overvoltage protection
The ICE5BR3995CZ, part of Infineon’s 5th generation fixed frequency CoolSET™ family, is a highly integrated current-mode controller including a 950 V CoolMOS™ superjunction MOSFET.
Especially in an unstable grid environment, an adjustable line overvoltage protection with an auto-resume scheme is incorporated to protect against operating beyond the normal input range.
Thanks to the integrated MOSFET, the support of an ultra-wide input voltage range as commonly associated with single-phase smart metering and industrial application is possible. In addition, snubber circuitry can be optimized further to enhance the efficiency/standby performance of the converter.
Available in the DIP-7 package, the ICE5BR3995CZ offers a high level of integration that provides a comprehensive suite of protection features, frequency jittering to minimize EMI, and frequency reduction in tandem with the decrease of load to improve overall efficiency. On top, the active burst mode improves light-load/standby performance.
