E522.31 is a fixed frequency switch-mode high voltage LED power supplier and controller with high efficiency. Integrated highside sensing allows topologies related to GND (Boost-to-GND or SEPIC) as well as related to input voltage (Boost-to-battery or Buck-to-battery, particularly in harsh automotive environments.
The 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. short- and open load detection, over-temperature shutdown and undervoltage lockout are implemented.
