DC DC Converters

DC DC Converters are an efficient way to transform one voltage level into another, providing isolated power supplies for a wide range of applications. It allows the output to be changed between different input voltages and output current. DC DC converters are typically used in industrial, commercial and consumer applications where reliable, low cost power supply is needed.

TMR 3-7215WIR Application Field and Working Principle

The TMR 3-7215WIR isolated dc-dc converter is a wide input voltage range, miniature isolated dc-dc converter module. It is designed for very wide range of applications. It accepts input voltage up to 32V and provides an isolated output voltage of 3.3V at up to 1.5A. The output is always regulated, even if large changes occur in the input voltage. The TMR 3-7215WIR has current sensing and voltage monitoring features, which makes it suitable for various applications where these features are important.

The TMR 3-7215WIR isolated dc-dc converter works by using a forward converter topology. The forward converter takes the input voltage and switches it to create a high frequency data stream which is then filtered and regulated through the output voltage. The input voltage is regulated to the output voltage by an integrator circuit that also serves to create the separation between the input and the output voltage. The output voltage is then achieved by the feedback loop compare section, which detects any deviation from the target output and provides the integrator circuit with the necessary corrections to keep the output voltage stable.

The TMR 3-7215WIR also has current sensing and voltage monitoring features, which makes it suitable for various applications where these features are important. It has the ability to detect current leakage to ground, which can be used to detect shorts across the output. It also includes voltage cascading which allows it to scale the output voltage up or down, providing an extremely wide input voltage range.
