The TPIC2701N is a high-voltage, low on-resistance, n-channel field-effect transistor (FET) switch. It has been designed to reduce power dissipation and minimize switching time, making it applicable to a range of applications such as switching power supplies, LED drivers, computation products, and industrial automation equipment. This article will focus on the application field and working principle of the TPIC2701N.

Application Field

The TPIC2701N is particularly suitable for many switch-mode power supply circuits. Its fast switching properties make it suitable for high-frequency applications. It also offers low on-resistance with virtually no resistance rise over a wide range of operating temperature. This makes it suitable for applications like end-of-line switching, multiple power rail switching, and constant-current High-Brightness LED (HB-LED) lighting. It also works in primary-side control of high-efficiency voltage mode switching regulators.

Another application field of the TPIC2701N is the industrial automation industry. In industrial automation applications, it is typically used in power switching solutions, such as 3-phase motor control. Its high efficiency, fast switching time and low switching losses make it an ideal choice for industrial automation applications.

Finally, the TPIC2701N can be used in a variety of computation product applications, such as portable computer power supply, level shifters for power rail control, and notebook voltage regulators. It also supports secondary-side synchronous rectified forward converters. Its good over-current protection capabilities and wide operating temperature range make it ideal for computation product applications.

Working Principle

The working principle of the TPIC2701N is based on the FET switch technology. A FET switch is made up of a gate, drain, and source. When the switch is "ON", current can flow from the source to the drain. The resistance between the drain and the source is low. When the switch is "OFF", the resistance between the drain and the source is high, so no current can flow. The gate determines the switch\'s state. By applying an appropriate gate voltage, the switch can be turned "ON" and "OFF". This is the essential principle of the TPIC2701N.

The TPIC2701N is designed with a maximum operating voltage of 20V. This allows it to securely and reliably handle higher voltage loads. It also provides a fast switching speed, allowing it to quickly switch from "ON" to "OFF" states, which reduces power dissipation and allows for faster control of the load. The low on-state resistance of less than 0.35 Ohms also reduces power losses significantly.

The TPIC2701N also provides good short circuit protection. Its low on-state resistance and high breakdown voltage ensure that it can handle short circuit conditions, reducing the risk of damage to other devices in the circuit. As mentioned before, the TPIC2701N also has a wide operational temperature range of -55°C to +150°C, which further enhances its reliability.

To summarize, the TPIC2701N is a high-voltage, low on-resistance, n-channel FET switch designed for applications such as switching power supplies, LED drivers, industrial automation, and computation product applications. Its fast switching, low on-state resistance, wide temperature range, and good short circuit protection make it an ideal choice for these applications.
