E52233A61C

E522.33 is part of a family of fixed frequency switched-mode high voltage LED power supplies and controllers with high efficiency. Integrated high-side sensing allows topologies related to the supply input (Boost-to-Battery) or to GND (Boost-to-GND). The device is suitable for operation in boost-, buckboost-, SEPIC- and buck-topologies, particularly in harsh automotive environments.The constant switching frequency is adjustable up to 600kHz by an external resistor or can be synchronized in Master-Slave configurations with other devices.Multiple control- and monitoring functions, e.g. shortand open load detection, over-temperature shutdown and under-voltage lockout are implemented.
