IP1201TR Application Field and Working Principle

The IP1201TR belongs to the DC-DC switching regulators (also known as DC-DC converters) of PMIC – Voltage Regulators. It is a synchronous step-down DC-DC converter with three-phase topology that covers an input voltage range of 5V to 16V, offering a power solution up to 120W, and with an output voltage range of 0.9V to 5V. It is particularly well-suited for Gener-Interface-Bus (GIP) applications.

Applications

The IP1201TR is an excellent choice for a wide range of applications ranging from industrial, communication, and consumer products. It can be used in wireless base station power supplies, server power components, factory automation equipment, down converters for video/audio systems, and low voltage power supplies for medical instruments. It is also ideal for battery-powered devices, portable media players, and digital cameras. With its low power consumption, it even guarantees high efficiency with low amount of heat generation, high power density, and low acoustic noise.

Working Principle

The IP1201TR operates on the principle of a voltage generated from the input voltage and switched to the output voltage. It includes two stages, the first stage is the Power Stage and the second stage is the Control Stage. The Power Stage consists of a high-side driver, a low-side driver, a primary-side switch, and a secondary-side switch, while the Control Stage has a controller, a current mode controller, and a gate driver. To deliver the desired output power, the IP1201TR relies on synchronous rectification and pulse width modulation (PWM) controlled switching. The synchronous rectification operates at a higher power output and reduces power dissipation, while PWM control results in the output voltage being clamped to the desired voltage.

High Efficiency Mode

The IP1201TR also features a High Efficiency Mode (HEM) which helps to reduce the power losses, increase efficiency and power density. The HEM technique uses a new patented design technique to combine the synchronous rectification circuit into the PWM control loop. This results in improved performance, reduced noise, and higher efficiency. It also simplifies the power stage design and helps to increase the power density of the IC. In addition, the IP1201TR features protection features, low-battery protection, and load-protection, which allows it to be used in a vast array of applications.

Conclusion

In conclusion, the IP1201TR is an excellent choice for a wide range of applications. Its two-stage configuration, synchronous rectification and pulse width modulation control make it an efficient, reliable and durable choice for industrial, communication and consumer products. Its protection features, low-power consumption and high power density also make it well-suited for battery-powered devices, portable media players and digital cameras. Thus, the IP1201TR is a great choice in terms of performance, efficiency, and cost-effectiveness.
