Absolute Maximum Ratings Parameter Min Typ Max Unit Notes Continuous Input Voltage -0.3 - 15 V Voltage on SEQ terminal -0.3 - VIN V Voltage on SYNC terminal -0.3 - 12 V Voltage on PG terminal -0.3 - 6 V Operating Ambient Temperature -40 - 85 °C Storage Temperature -55 - 125 °C Note: Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability. Input Specifications Parameter Min Typ Max Unit Notes Operating Input Voltage 4.5 - 14 V Input Current (full load) - - 20 A VIN=4.5V to 14V - 42 - mA Vo=0.69V, VIN=10V, IO=0, module enabled Input Current (no load) - 74 - mA Vo=3.3V, VIN=12V, IO=0, module enabled Input Stand-by Current - 3 - mA VIN = 12V, module disabled Input Reflected Ripple Current (pk-pk) - 43 - mA 5Hz to 20MHz, 1μH source impedance; VIN =4.5 to 14V, IO= IOmax I 2t Inrush Current Transient - - 1 A 2s Input Ripple Rejection (120Hz) - 45 - dB Turn-on Threshold - 4.45 - V Turn-off Threshold - 4.2 - V Hysteresis - 0.25 - V CAUTION: This converter is not internally fused. An input line fuse must be used in application. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 20A. Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information. Note: Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions. |
