DS_B70SR24125_10222013 E-mail DCDC@delta.com.tw http://www.deltaww.com/dcdc P5 FEATURES DESCRIPTIONS Output Over-Current Limit and Short Protection The modules include internal output over -current limit (OCL) and short circuit protection (SCP) circuits, the OCL set point is lower than that of the SCP; T he response of SCP circuit is much fast than that of the OCL circuit. The slowly increase of the output current will let module enter OCL protection when the current exceeds the OCL set point, while the fast increase of the output current will let module enter SCP when the current exceeds the SCP set point. When the m odules enter OCL protection, the output voltage will decrease while the output current is kept constant, the output voltage will soft start to set point when the overload condition is removed. The module will enter hiccup mode whe n it triggers the SCP set point . The module will try to restart after shutdown. If the overload condition still exists, the module will shut down again. This restart trial will continue until the overload condition is removed. Output Over-Voltage Protection The power module includes an internal output over-voltage protection(OVP) circuit, which monitors the voltage on the output terminals. If this voltage exceeds the OVP set point, the module will shut down, and then restart after a fixed delay time (hiccup mode), please refer to figure6 for detail. Over-Temperature Protection The over -temperature protection consists of circuitry that provides protection from thermal damage. If the temperature exceeds the preset temperature threshold the module will shu t down,and all components will not exceed their absolute maximum temperature ratings.The module will restart after the temperature is within specification. Enable On/Off B70SR24125C has Enable control function. The Enable PIN is design ed on the primary side of converter, the converter will turn on when the Enable PIN connected to VIN+, and turn off when the Enable PIN connected to VIN- or floating. Figure 13: suggested Enable connection Input Reverse Voltage Protection The input reverse vol tage protection is provided by an diode on the input line, the standoff voltage for the reverse protection shall be no less than -106V.
