The TPS62125EVM-044 is an evaluation module for a synchronous 4A, 8 MHz Step-Down Converter. It is classified under Evaluation Boards -DC/DC & AC/DC (Off-Line) SMPS, due to its exclusive attribute of controlling the output voltage efficiently in both AC and DC with a synchronous rectifier controller from Texas Instruments. This device suits designs that place prominent emphasis on the quality of power supply, due to its salient features which ensures optimum power delivery, preferably in consumer electronic applications. This module does well to guarantee efficient performance and high level of precision.The TPS62125 is like other product from the TPS62100/2 platform, a simple and efficient synchronous step-down converter with integrated high side MOSFET and low side MOSFET. It uses full power pulse width modulation (PWM) and synchronous rectification to run with an input voltage range of 4.5 V to 5.5 V and an output voltage range of 0.8 V to 5 V. The operating frequency is programmable allowing 6 different ranges, from 100 KHz to 1.2 MHz. The TPS62125EV is cost effective and highly and ideally suited for efficient power management solutions in battery-powered, spacec saving consumer base electronics application.

The built-in MOSFETs of the TPS62125EV device are also capable of delivering up to 4A of continuous output current with up to 94% of efficiency and the device also has separate power on and enable inputs, that allow the user to achieve light load regulation performance and low power dissipation in shutdown mode. An integrated internal current-limit and thermal-protection feature provide robust circuit design and safety protection. Moreover, it is rated to operate over an extended temperature range of -40℃ to +85℃ This highly convenient attribute of thermal protection also reduces the need for external components and allows the use of maximum component packages with the smallest solution size.

The TPS62125EVM-044 evaluation module measures 29 mm by 18 mm and is supplied with the highly popular Texas Instruments’ board evaluation software. The module includes an embedded open loop-based resonator, that allows reliable, easy and accurate tuning of the loop, for a variety of applications. The module features a very low parts count and a comprehensive array of test points which enable design engineers to analyze performance.

In summary, the TPS62125EVM-044 evaluation module demonstrates outstanding power management performance, high efficiency, low thermal sensing, true high-side & low-side current monitoring and a wide input voltage range. It helps the user to design faster start-up times between off states and power sequence in-rush current reduction. This module with its unique characteristics is a compact solution for powering almost all consumer electronic applications. It also does well to reduce the time-to-market of the end application.
