This facilitates ease of resistor selection and contributes to a decreased number of parts for customer inventory if the TRIM pin is being utilized. OUTPUT ENABLE The ALQ15 comes with an Enable pin (PIN 2), which is primarily used to turn ON/OFF the converter. Both a Positive (no part number suffix required) and a Negative (suffix “N” required) Enable Logic options are being offered. Please refer to Table 2 for the Part Numbering Scheme. For Positive Enable, the converter is turned on when the Enable pin is at logic HIGH or left open. The unit turns off when the Enable pin is at logic LOW or directly connected to -VIN. On the other hand, the Negative Enable version turns on when the Enable pin is at logic LOW or directly connected to -VIN. The unit turns off when the Enable pin is at Logic HIGH. OUTPUT OVER VOLTAGE PROTECTION (OVP) The Over Voltage Protection circuit will shut down the entire converter if any of the two output voltages exceeds the OVP threshold limits. The converter will automatically recover once the fault is removed. OVER CURRENT PROTECTION (OCP) The Over Current Protection circuit will shutdown the converter if any of the load current of either output reaches the OCP threshold limits. The unit will automatically recover once the over current condition is removed. See Figure 12 for typical output characteristic under an over current condition. OVER TEMPERATURE PROTECTION (OTP) The Over Temperature Protection circuit will shutdown the converter once the sensed location reaches the OTP range. This feature prevents the unit from overheating and consequently going into thermal runaway, which may further damage the converter and the end system. Such overheating may be an effect of operation outside the given power thermal derating conditions. Restart is possible once the temperature of the sensed location drops to less than 110 °C. |
