LM3495EVAL

LM3495EVAL is a evaluation board designed to accommodate a variety of DC/DC & AC/DC (Off-Line) SMPS applications. This evaluation board allows for designers to find out the technical performance data of the target component in both DC/DC and AC/DC configurations. It is targeted at engineers and technicians who needs to design basic SMPS for a wide range of applications involving power conversion.

Features

• Wide range of applications including Off-Line AC/DC power, DC/DC power, etc.
• Designers can evaluate the performance and technical data of the targeted component
• Supports the use of both linear and switching power supplies

Working principle

The basic fundamentals of the LM3495EVAL is a set of two amplifiers. The first amplifier is a voltage-divider working as an input signal source. This voltage-divider provides a reference voltage for the second amplifier which compares the input signal with the reference voltage. This output from the second amplifier is then fed into the voltage regulator or through the opto-isolators in order to provide a stable power output. The LM3495EVAL also includes various monitoring features such as over-current protection, over-voltage protection, etc. which respond to the over-current or over-voltage condition and shut down the power supply.

The LM3495EVAL evaluation board can be used with both linear and switching power supplies. For linear supplies, the input signal is passed through the opto-isolator to the voltage regulator, which provides a stable power output. For a switching power supply, the output of the first amplifier is passed through the opto-isolator to the voltage regulator, which is then connected to the switching power supply (used to provide a higher power output than a linear supply). The voltage regulator and switching power supply are then used to provide a stable power output.

Conclusion

The LM3495EVAL is a versatile and powerful evaluation board which allows for designers to test a range of DC/DC & AC/DC (Off-Line) SMPS applications. It is designed with efficiency and robustness in mind and provides a reliable and stable source of power for a variety of applications. The use of two amplifiers allows for accurate monitoring of the target components and the use of opto-isolators and voltage regulators provide a stable power output. This evaluation board is an ideal choice for engineers and technicians looking to design basic switching and linear power supplies.
