TPS546C20AEVM2-746

The TPS546C20AEVM2-746 evaluation module is an integrated circuit designed to manage DC/DC, AC/DC and off-line SMPS (switched-mode power supply) power stages. This evaluation board integrates a TPS546C20 Single-Phase synchronous buck controller with and integrated FET driver and a TPS5661A buck regulator. This feature allows for a highly efficient power conversion with high current output capabilities in a small form factor.

This evaluation module is typically used in applications such as servers, routers, core processors, etc. that require processors to have high efficiency and low power consumption. The TPS546C20AEVM2-746 uses a synchronous buck topology to regulate the input voltage and deliver a constant output voltage regardless of input voltage or load current. It also incorporates advanced protection features to protect against overcurrent and over-temperature conditions and to reduce electromagnetic interference (EMI).

The TPS546C20AEVM2-746 works by using a pulse width modulation (PWM) control scheme to ensure accurate and reliable power delivery. By changing the width of the PWM pulses, the controller can control the output voltage of the buck converter. The PWM signal is generated using an internal oscillator, and the frequency can be adjusted to optimize the efficiency of the power stage. The control loop of the TPS546C20AEVM2-746 also includes an internal comparator and error amplifier, which are used to compare the feedback voltage to a reference voltage. When the feedback voltage falls below the reference voltage, the controller increases the duty cycle of the PWM signal to compensate for the sudden load current change.

The TPS546C20AEVM2-746 integrates a TPS5661A buck regulator, which provides a constant output voltage in the event of a line voltage dip or surge. The TPS5661A also provides an overcurrent protection feature to prevent damage caused by unexpected increases in line current. In addition to this, the evaluation module is also equipped with several protection features that protect against over-temperature and over-voltage conditions.

The TPS546C20AEVM2-746 is a highly efficient and reliable evaluation board for DC/DC, AC/DC and off-line SMPS power stages. Its advanced protection features, integrated FET driver, and high current output capabilities make it an ideal platform for applications that require low power consumption and high reliability. The TPS546C20AEVM2-746 is a versatile evaluation board that can be used for a wide range of applications.
