Description

The Austin LynxTM 24V series SMT power modules are non-isolated DC-DC converters in an industry standard package that can deliver up to 48W of output power with a full load efficiency of 94% at 12Vdc output voltage (V 24Vdc). These modules operate over a wide input voltage range (V regulated output voltage from 3 to 6Vdc (AXB030) and 5 to 15Vdc (AXB050), programmable via an external resistor. Standard features include remote On/Off, adjustable output voltage, remote sense, over current and over temperature protection.

Absolute Maximum Ratings

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.

CAUTION: These power modules can be used in a wide variety of applications ranging from simple standalone operation to an integrated part of sophisticated power architectures. To preserve maximum flexibility, no internal fuse has been provided. Also, extensive safety testing has shown that no external fuse is required to protect the unit. However, it is still recommended that some type of current-limiting power source be used to protect the module and evaluated in the end-use equipment.
