The TPS2061EVM-290 is an evaluation module designed for power designs that require Adaptive On-Time (AOT) control. It has the ability to regulate current up to 5 Amps and can be used to evaluate many types of power supplies. The board includes a low-side referenced MOSFET, current sense resistor, high frequency current sensing circuit, undervoltage lockout with hysteresis, and an output voltage feedback circuit for AOT control.

Adaptive On-Time (AOT) is a primary-side control topology whereby an output voltage is maintained by adjusting the “on-time” duty cycle of the MOSFET switch. The output voltage is monitored using the low-side sensing circuit, and the MOSFET switching device. As the output voltage deviates away from the target voltage, the “on-time” duty cycle of the MOSFET is increased or decreased accordingly to achieve the desired output voltage. This technique allows for the device to maintain a stable output over a wide operating range.

The TPS2061EVM-290 is an ideal evaluation board for evaluation and development of AOT based Power Supplies. It eliminates the need for costly custom development boards and development time by providing an easy to use platform for many different types of power supplies. The evaluation module operates by measuring the output voltage or current and adjusting the switching duty cycle of the MOSFET accordingly. This method contributes to the module’s high efficiency and excellent line regulation. Additionally, the board includes EMI input filters and an optional output filter that improve the peripheral emissions of the power supply.

The TPS2061EVM-290 evaluation module is ideal for power design engineers looking for an easy to use platform to evaluate and develop AOT based power supplies. It features four outputs that can be adjusted and monitored independently. It also includes onboard diagnostics such as temperature, current, and voltage, as well as an array of protection circuitry to prevent damage to the device if it is overloaded or operated under extreme conditions. With its ability to control up to 5 Amps of output current, the TPS2061EVM-290 is an ideal solution for applications such as motor control, LED lighting, server power supplies, and automotive systems.

In summary, the TPS2061EVM-290 evaluation module is an ideal tool for the evaluation and development of power supplies that require adaptive on-time control. This module is designed to enable power designers to quickly and efficiently evaluate and develop power supplies. It features a low-side referenced MOSFET, current sense resistor, high frequency current sensing circuit, undervoltage lockout with hysteresis, and an output voltage feedback circuit for AOT control. It also offers a wide range of features such as EMI input filters, an optional output filter, onboard diagnostics, and protection circuitry that can prevent damage to the device if it is overloaded or operated under extreme conditions. This makes the TPS2061EVM-290 evaluation module an ideal solution for application such as motor control, LED lighting, server power supplies, and automotive systems.
