The TPS563201EVM-715 is a high efficiency, low quiescent current, low noise, synchronous buck converter evaluation module that can generate an output voltage from 0.81V to 3.3V. It operates from an input voltage ranging from 4.5V to 17V and provides a programmable, maximum output current of 1.2A. This module is equipped with an Analog Devices ADuC7060 microcontroller running custom firmware and a 5V low dropout linear regulator. There are also two user adjustable resistors (RPROG and RFB) to set the output voltage.

The TPS563201EVM-715 is part of the Evaluation Modules for DC/DC & AC/DC (Off-Line) SMPS. These modules are designed for use by engineers to test, evaluate, and develop their power supply applications. The modules come with full documentation and schematics detailing features and function, as well as providing customization instructions for specific needs. Evaluation boards are typically populated with select components so that engineers can quickly evaluate components for their applications and ensure performance compliance.

The working principle of the TPS563201EVM-715 is based on a synchronous buck converter. This type of converter uses two switches to regulate the output voltage; a high-side switch and a low- side switch. The high-side switch is connected to the input voltage and is used to regulate the primary current. The low-side switch is connected to the output voltage and is used to regulate the secondary voltage. This converter operates in two different modes; continuous conduction mode (CCM) or discontinuous conduction mode (DCM). While in CCM, the inductor current does not go to zero during each switching cycle and in DCM, it does.

The TPS563201EVM-715 is a single-inductor buck converter capable of output voltages from 0.81V to 3.3V. A fast-response, low-noise voltage regulator with on-chip controls is used to control the gate drive and switching of the converter switches, resulting in high efficiency and low quiescent current. Furthermore, the converter operates with a switching frequency of 1.2MHz. This ensures fast transient response and low output voltage ripple.

In addition, the TPS563201EVM-715 includes over-voltage, over-current, and thermal shutdown features as protection against abnormal operating conditions. It also includes an adjustable soft-start, allowing the output voltage to ramp up slowly to reduce inrush current.

In summation, the TPS563201EVM-715 is a versatile, high efficiency synchronous buck converter evaluation module that is ideal for a wide range of applications including DC/DC converters, buck regulators, and Power over Ethernet (PoE) systems. It is easy to use and customize for specific needs and is an excellent choice for developers and engineers needing an efficient and reliable power supply module.
