Application Field

The AP2160KTR-G1 is designed for use in linear regulator applications where multiple output voltage settings are required. Typical applications include power supplies for notebook computers and PDAs, cameras, battery charging circuits and low-power embedded systems. The AP2160KTR-G1 also features an onboard temperature sensor which can be used to monitor and optimize the power supply system performance, as well as improve system stability and safety.

Working Principle

The AP2160KTR-G1 is designed to work with a variety of linear regulator architectures. The device controls the output voltage of the regulator by sensing the output voltage and comparing it to a programmable voltage reference. The device uses an analog current-mode control-loop stage to regulate a linear regulator’s output voltage to a stable value by comparing the voltage at the regulator output to the programmable voltage reference. The device features short-circuit current limiting with fold-back current limiting and temperature protection. When an over temperature or short-circuit condition is detected, the linear regulator output voltage is reduced to avoid damage to the system.

The AP2160KTR-G1 has a stand-by current of typically 0.01µA and maximum of 0.2µA when disabled. This low static current feature enables the system to operate under low-power conditions. The AP2160KTR-G1 is capable of providing up to a 5A output current. The device offers excellent line and load transient performance ensuring that the regulator delivers a smooth, reliable output voltage.

Conclusion

The AP2160KTR-G1 is a linear regulator controller that offers excellent power supply design flexibility for mobile computing applications. The device offers excellent current limiting, output voltage and temperature monitoring, and load and line transient performance, making it ideal for use in battery powered applications. The device is designed to work with a variety of linear regulator architectures and offers a stand-by current as low as 0.01µA. This ensures that the system can operate under low-power conditions and allows for greater design flexibility while still providing excellent output voltage stability.
