DESCRIPTION
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.

NOTE
1. During the test of input reflected ripple current, the input terminal must be connected to a 12 uH inductor and a 220 uF electrolytic capacitor.
2. Point B, which is for testing the output voltage ripple, is 25 mm (0.98 in.) away from the Vout(+) pin.
