Introduction to the LM5008EVAL

The LM5008EVAL evaluation board is an off-line AC/DC and DC/DC small, medium, and large power supply (SMPS) design platform based on Texas Instruments’ LM5008 IC. The board supports a wide range of voltage and current configurations, allowing designers to quickly prototype and prove power supply system concepts and sub-systems. This evaluation board is also capable of testing the LM5008 IC performance of powering higher power dissipation products such as server and telecom power supplies.

Application Field of the LM5008EVAL

The LM5008EVAL is an ideal development platform for a variety of applications, including equipment for consumer, automotive, and industrial applications. Additionally, the evaluation board can be used in stand-alone power supplies for high power products such as servers, telecommunication systems, and even high power multiple output power supplies.

Working Principle of the LM5008EVAL

The LM5008EVAL board uses an input voltage ranging from 5V up to 24V and provides a regulated output voltage range of 0.6V to 20V. The board’s output is protected against overloads, short circuits, and overtemperature. The board automatically enters into a power saving mode in the event of an overload.The LM5008 IC used in the evaluation board is a low-side isolated switch-mode current-mode (CM) controller IC. The device’s main features are: an internal soft start capability, protection and control logic, a controlling IC, and an output stage. This IC works with a fixed frequency of 200kHz and operates in the current mode to ensure fast line and load transient response times. The board contains all the necessary protection functions, such as short circuit protection, overload protection, and overtemperature protection, to guarantee reliable operations.The main section of the evaluation board is based on the CTR-5712 control and protection circuit. It combines logic control, gate-driving, power regulation, protection, and other functions with dedicated switching signals. The primary function and feature of this device is to provide the reference voltage (VREF) to the IC for use as either a feedback voltage or a precision reference voltage.

Conclusion

The LM5008EVAL evaluation board is an off-line AC/DC and DC/DC SMPS design platform based on the Texas Instruments’ LM5008 IC. It is a great development platform for a wide range of applications. The board works by using an input voltage ranging from 5V up to 24V and providing a regulated output voltage range of 0.6V to 20V. The main sections of the evaluation board are based on the CTR-5712 control and protection circuit to provide the reference voltage to the IC. The LM5008EVAL offers a wide range of voltage and current configurations, and it also contains all the necessary protection functions to guarantee reliable operations.
