The TLV62065EVM-719 is an evaluation board for the TLV62065-Q1 buck controller, featuring an efficient synchronous rectification (SR) buck regulator. It has the capability to operate from an input voltage between 4.5 V and 17 V, and can produce an adjustable output voltage of up to 17 V. The TLV62065EVM-719 is suitable for applications such as offline POL (Point of Load) DC/DC conversion, automotive engine control, portable industrial applications, and isolated flyback converters.

The TLV62065EVM-719 features an IC package with a 7-mm-by-7-mm footprint. It features an 8-pin SOIC, a 7-mm-by-7-mm outline with one additional pin used as the output voltage sensing pin (ADJ). It also offers a 30-percent increase in efficiency compared to conventional solutions, allowing for higher load currents and better power dissipation.

The TLV62065EVM-719 operates in voltage-mode control (VMC) and has a switching frequency of up to 500 kHz. It features an adjustable output voltage with current-mode control (CMC). It has a wide operating range and is capable of providing power up to 1A. The controller features a wide fault range and protection features, including over-voltage, under-voltage, thermal shutdown, cycle-by-cycle current limit, and reverse voltage protection.

The TLV62065EVM-719 has a robust design that is able to tolerate voltage transients on the input and output. The board has an adjustable soft start and a enable/disable pin that can be used to put the output voltage into low-power state. In addition, the board has a user-selectable output current limit feature to further reduce output current during fault conditions. The board also includes an optional over-voltage protection (OVP) to protect the load from possible overloads.

The working principle of the TLV62065EVM-719 is based on a synchronous rectification bucktopology. The controller measures the output voltage and adjusts the switching frequency in order to maintain the desired voltage. The switching mode of the TLV62065EVM-719 is current-mode control, which is an effective way to reduce noise, line regulation, and switching loss.The controller also offers a voltage-mode control mode for a wider operating range.

The TLV62065EVM-719 is an ideal tool for engineers to evaluate the performance of the TLV62065-Q1 buck controller. The board comes with various external components that help to ensure proper function and protection. The board is also stackable for debugging, allowing engineers to connect multiple boards together to form a larger testing and evaluation unit. The stackable version of the board also offers the ability to monitor and compare multiple power rails in one easy setup.

In conclusion, the TLV62065EVM-719 is an evaluation board that is suitable for high-efficiency DC/DC and AC/DC (off-line) SMPS applications. It features an 8-pin SOIC package, which makes it suitable for space-constrained applications. It features voltage-mode and current-mode control, both of which offer a wide operating range and robust protection to protect the load from possible overloads. The board is stackable for debugging and allows for monitoring multiple power rails. Lastly, the board comes with various external components to ensure proper function and protection.
