The LMZ31506HEVM-692 is part of Texas Instruments’ family of Evaluation Boards for DC/DC & AC/DC (Off-Line) SMPS. This standalone evaluation module is designed as a platform to showcase TI’s LMZ31506HE DC/DC converter. The board provides an integrated circuit evaluation environment for DC/DC step-down converter, with no additional connection or external components needed. The board is designed with a single power symbol magnetics transformer offering continuous operation up to 6A with 92% efficiency for an input voltage of 8V to 40V.

This evaluation module offers several features that allow for flexibility in design and productivity. It has a built-in protection circuit to protect the system from reverse voltage, short-circuit current limiting, and over temperature protection. Additionally, the board has several control and monitoring peripherals that help with the testing of the various features of the converter, such as its ambient temperature range, input voltage range, and current detection capabilities. It also offers onboard ports that enable customers to evaluate the LMZ31506HE’s various features, such as feedback voltage monitoring, PWM control, and dynamic response to load transients.

Clients are able to quickly and easily evaluate the LMZ31506HE on this evaluation board. The board is powered by an input voltage of 8V to 40V, and provides 3.3V, 5V, 12V, and auxiliary outputs. This input power can be connected using a CC/CV supply, a battery, or through a conventional transformer. To begin testing, the customer simply connects their input and output source using the available ports on the evaluation board, then begins controlling the LMZ31506HE via the onboard MCU.

The LMZ31506HE works by using its integrated high-side and low-side FETs to implement a buck converter circuit. This buck topology allows the LMZ31506HE to convert the input voltage to the required output voltage and current. The output voltage is adjusted by changing the duty cycle of PWM signal sent into the module’s feedback and control nodes. The LMZ31506HE also has a built-in soft-start feature which enables it to deliver a controlled output at power up, and to respond quickly to load transients for improved system stability.

The LMZ31506HE allows for higher efficiency and better performance over more traditional switching methods, with less heat dissipation and improved size-to-performance ratio. This makes a buck topology more ideal for applications requiring low-voltage/high-current solutions. The range of protection features also helps to eliminate the need for external components in order to achieve the desired level of system safety and reliability.

Overall, the LMZ31506HEEVM-692 provides an ideal testing environment for clients to gain a better idea of the functionality of the LMZ31506HE. The board is designed with an integrated circuit evaluation platform for no additional connection or external components required, and offers several features which enable customers to easily evaluate the performance of the LMZ31506HE. Additionally, its buck topology offers a wide range of efficiency and performance solutions for customers who require a high-power/low-voltage solution for their various applications.
