TC1303C-VP0EUN Application Field and Working Principle

TC1303C-VP0EUN is a type of voltage regulator from the PMIC voltage regulators linear+switching category. It integrates P-channel and N-channel MOSFETS into a compact, monolithic device and comes in a unique dual flat-no-lead package. It has applications in both positive and negative linear, and also in positive simple switch-mode regulation. It has wide input parameters and requires very small external components.

Applications

The TC1303C-VP0EUN can be used in various applications, including power system supplies, automotive, consumer electronics, industrial, mobile, and wearable applications. It is a great solution for low voltage, high power, and low EMI applications. It is capable of supplying up to 6A from a single device, depending on the application. It features low drop-out voltage, making it ideal for low-voltage systems.

Working Principle

The TC1303C-VP0EUN is based on a linear and switching regulator system. The linear portion drives the MOSFETs with an external P-channel and an N-channel MOSFETs, while the switching portion drives the MOSFETs with an Internally generated PWM signal. The switching begins when the output voltage is higher than the target voltage, causing the P-channel MOSFET to switch off, and the N-channel MOSFET to switch on. The linear portion ensures that the output voltage is maintained at the target voltage. When the input voltage drops, the linear portion is used to maintain the output voltage, until the load increases, at which point the switching portion takes over, ensuring the output voltage remains at the target voltage.

Conclusion

The TC1303C-VP0EUN is an ideal solution in power system supplies, automotive, consumer electronics, industrial, mobile, and wearable applications. It provides high power output, low EMI, and requires very small external components. It is powered by a linear and switch-mode regulation system and can provide up to 6A of power, depending on the application. It can be used in both positive and negative linear, as well as positive switch-mode regulation. It also has low drop-out voltage, making it great for low-voltage systems.
