TPS2071DAPR

TPS2071DAPR Application Field and Working Principle

The TPS2071DAPR is a power management integrated circuit (PMIC) from Texas Instruments. It is a specialized power management device designed for DC/DC buck functions. The device includes an integrated series-mode DC-DC converter, high-side and low-side Logic-level MOSFETs, and advanced power management features that make it ideal for power supply applications. The device can be used to provide accurate regulation of output voltage and current levels, as well as providing short-circuit and over-temperature protection.

The TPS2071DAPR’s input power range is 6.5 to 19V, with an effective output range of 0.6 to 12V. This makes it suitable for applications that require a low-powered output such as cell phones, laptops and other portable devices. It also has a wide operating temperature range from -40 to +105 degrees Celsius. The device supports current mode, voltage mode, and pulse width modulation (PWM) operation modes.

The TPS2071DAPR is designed to provide a reliable, high-efficiency and cost-effective DC/DC conversion solution. It has a maximum supply current of 2.2A, a minimum output current of 0.5A, a switching frequency of 800kHz, and an efficiency of up to 94%. It also has short-circuit and over-temperature protection features.

The TPS2071DAPR is designed to operate in a single package solution and includes digital control, rectification, overvoltage, undervoltage, and overcurrent protection. The device has remote-sensing inputs that can sense the output voltage at the load and adjust the output voltage accordingly. This makes it suitable for applications where the output load varies widely, such as big servers.

The device features a dual-stage power management architecture to ensure optimal efficiency and power isolation. This makes it ideal for applications such as laptop, mobile or industrial controlling system. The TPS2071DAPR can be used to provide precise and stable 6.5 to 19V output power, with a programmable output voltage of 0.6 to 12V and an adjustable current limit from 0.5 to 2.2A.

The TPS2071DAPR is an integrated PMIC and provides a total power management solution with superior load transient and ample short-circuit protection. It also features high-efficiency synchronous rectification and low-noise operation. With its integrated MOSFETs, it is able to provide a small-sized, reliable and cost-effective solution for DC/DC buck functions for an array of applications.
