KA1M0680RBYDTU

KA1M0680RBYDTU is an offline switcher, part of the PMIC (power management integrated chip) family of components. PMICs are used to reliably convert, store and distribute energy to power a wide range of systems. The KA1M0680RBYDTU is an integrated solution that provides the following features and functions to aid the AC-DC conversion and switching needs of a system:

• Constant-current output: KA1M0680RBYDTU uses a PI (proportional integral) controller to provide a constant-current output from a wide input voltage range. The part provides up to 3.3A current at a maximum 80V output voltage.
• Low-Side Gate Drive: The KA1M0680RBYDTU provides a low-side gate drive to reduce power losses that are commonly associated with higher power switches.
• Current Mode Control: KA1M0680RBYDTU incorporates current-mode control to improve system efficiency, particularly with inputs less than 20V or non-linear loads.
• Protection Features: The KA1M0680RBYDTU provides protection against over-voltage, over-temperature, and short-circuit via internal power-cycle and timeout.
• Soft-Start/Inrush Control: KA1M0680RBYDTU’s soft-start capability supports low-inrush current during system startup, thereby reducing stress on power supply components.
• Load Detection: KA1M0680RBYDTU has the ability to detect load change and respond quickly to maintain system stability.

The KA1M0680RBYDTU integrates these features and functions within a single 7-pin SC-70 package. This integration simplifies designing into applications that need a reliable AC-DC offline switcher. KA1M0680RBYDTU has a working principle of turning “on” the output synchronous rectifier after the output capacitor is charged, when the power input reaches a certain level. It will then continue to charge the output capacitor until the output capacitor\'s UVLO (Under Voltage Lock Out) threshold is reached. As the input voltage decreases, the output voltage will decrease accordingly. Once the resistor R1 is in its upper limit, the output voltage will remain constant. The KA1M0680RBYDTU is a universal offline switcher designed to meet a wide range of power requirements. It is suitable for use in general-purpose AC to DC converter designs, as well as portable equipment and industrial, medical and recreational systems. Some general-purpose application examples for this switcher include:

• Battery chargers
• Telecom systems
• Portable medical and recreational equipment
• Adapter power supplies

The KA1M0680RBYDTU integrates all the features and functions necessary to provide reliable, efficient, AC to DC conversion and switching for a wide range of industrial and consumer applications. It is designed to provide up to 3.3A output current with a maximum 80V output voltage in a standard 7-pin SC-70 package. Furthermore, it offers low-side gate drive to reduce power losses, current-mode control for improved power efficiency and protection features against over-voltage, over-temperature and short-circuit.
