The TPS54362BEVM evaluation module is an off-line switching mode power supply (SMPS) controller designed for an output power of up to 10 A. It is based on TI TPS54362 synchronous buck controller designed for universal AC voltage applications such as telecom, datacom, and industrial power supplies. It is equipped with on-board sensing, current limited startup, power limiting, and other features to ensure reliable operation and robust power conversion performance.

The TPS54362BEVM is based on TI\'s TPS54362, featuring a low start-up current (< 140 µA) and peak input current per voltage mode (less than 30 A). Its supply voltage range is from 0 V to 24 V. The maximum output power is 10 A, and the output voltage is adjustable up to 15 V. It has high side and low side peak current limit, current limit & current mode control, adjustable slope compensation, output voltage scaling, over-temperature protection, and adjustable under-voltage lockout (UVLO) thresholds to ensure a reliable power conversion and long-term performance.

Its operating principles include a clock-based PWM controller, a current sense amplifier (CSA) and a low-side driver. The PWM controller produces a triangular wave, which serves as the reference for an internal error amplifier. The error amplifier compares the reference wave with the feedback voltage from the CSA and adjusts the peak current of the low side driver accordingly. A slope compensation circuit limits the rise and fall times of the output currents protecting the output stage from overshooting. A high-side driver is activated when the current reaches the current limit threshold in order to switch off the load while in current limit mode.

In summary, the TPS54362BEVM is a DC/DC and AC/DC (Off-Line) SMPS evaluation module based on TI\'s TPS54362 synchronous buck controller for high efficiency, a wide input voltage range, and excellent thermal performance. It features current-sense amplifier, high side current limit, adjustable gain, over-temperature protection, and adjustable under-voltage-lockout (UVLO) thresholds. It is designed to simplify the development and evaluation of applications in the telecom, datacom, and industrial power supply circuits.
