KEY FEATURES
Input under Voltage Protection
Over Current Protection (Hiccup Mode)
Short Circuit Protection (Hiccup Mode)
Over Voltage Protection (Hiccup Mode)
Over Temperature Protection (Self-recovery)
Remote ON/OFF Control
The BR240 series DC-DC converter are high-efficiency and power density 1/8
brick isolation modules, rating output voltage 12V, output power 240W. This
series provide the standard 1/8 brick version and the PMBus compatible
version. The latter is compatible with the PMBus1.1 communication protocol,
backward compatible with the I²C/SMBus protocol, and providing Pre-bias,
output monitoring and current sharing functions. The BR240 series conform to
the RoHS6 requirement.
