Description

General part information

ICE5BR4780 Series

The ICE5BR4780BZ, part of Infineon’s 5thgenerationfixed frequency CoolSET™ family, is a highly integrated current-mode controller including an800 V CoolMOS™ superjunction MOSFET. It supports both isolated and non-isolated topologies such as flyback and buck as typical of biasing and offline auxiliary power supply. Regulation is made easy thanks to an integrated error amplifier for non-isolated topologies to enable direct feedback while minimizing the external BOM. Thanks to the integrated MOSFET, the support of a wider input voltage range is possible and snubber circuitry can be optimized further to enhance the efficiency/standby performance of the converter. Available in the DIP-7 package, the ICE5BR4780BZ offers a high level of integration that provides a comprehensive suite of protection features, frequency jittering to minimize EMI, frequency reduction in tandem with the decrease of load to improve overall efficiency. On top, the active burst mode improves light-load/standby performance.
