Nowadays, the demand for more power efficient and cost-effective DC/DC switching regulators has increased. This is because various applications require higher performance and more efficient solutions for power management in a variety of operating environments. The TC7660IJA is a monolithic integrated circuit (IC) which is a complete solution for devices that need to accurately and efficiently switch between a variety of DC/DC inputs. The TC7660IJA offers a combination of features that allow it to meet the requirements of a wide range of applications, from ultra-low-power measurements to high power applications.

TC7660IJA Features

The TC7660IJA has an integrated high-frequency, high-efficiency switching architecture that lets it switch up to 1A of peak current (peak current limit is adjustable) with a power efficiency up to 98%. It includes an internal correction network and provides an adjustable output voltage range of 0.7V to 24V. The in-package package circuitry eliminates the need for external components other than the power supply and a PCB conduction thermal management system. The TC7660IJA features a current-mode, 250kHz operation and adjustable frequency of 250kHz or 500kHz. This allows it to easily implement multiple power-supply configurations, such as a single-supply configuration, dual-supply (optional) configuration, and multiple fixed-output voltage options.

The TC7660IJA is designed for ultra-low power applications, such as portable audio devices, handheld electronic products, and computing modules. It is also suitable for medium to high power applications, such as powering industrial process controllers, server rails, and power boards. It offers an enable/disable function that helps reduce quiescent power consumption and increases system efficiency.

TC7660IJA Working Principle

The TC7660IJA is designed to provide highly efficient switching performance. It combines various functions into one single chip to make it easier for users to implement their circuits. The integrated circuit is designed to operate over a wide frequency range, from as low as 200kHz to as high as 500kHz. Its frequency is adjustable and it is designed for high-efficiency, high frequency operation. The integrated circuit is also designed to be power efficient and is capable of providing up to 98% efficiency in many applications. The integrated circuit also includes a correction network which helps reduce power losses.

The TC7660IJA works by using a synchronous buck topology. This topology is based on a Pulse Width Modulation (PWM) control system that keeps the output voltage constant by adjusting the frequency passing through the PWM signal. The PWM signal acts as a controller for the switching power circuit, setting the amount of time for which each switch stage is enabled. By varying the amount of time for which each switch stage is enabled, the power circuit can be controlled and accurately regulated.

The TC7660IJA includes a sense resistor network as part of its power supply control circuit. This network allows the output voltage to be monitored and adjusted according to the load. This ensures that the output voltage remains constant, even under changing loads. The circuit also includes an overvoltage protection circuit which provides a safety margin by helping to prevent the output voltage from exceeding the set maximum voltage.

Conclusion

The TC7660IJA is an integrated circuit which is suitable for a wide range of power management applications. It features a high efficiency, up to 98%, and an adjustable frequency of 250kHz or 500kHz. It is suitable for low to high power applications, such as powering portable audio devices, handheld electronic products, and computing modules. The TC7660IJA also offers an enable/disable function to help reduce quiescent power consumption and increase system efficiency.
