TPS40055EVM-002 has a wide range of application fields and working principles. It is intended for use with multiple types of DC/DC (direct current/direct current) and AC/DC (alternating current/direct current) switch-mode power supplies (SMPS). TPS40055EVM-002 is a complete evaluation board featuring the TPS40055 converter IC and a digital controller. The digital controller allows users to adjust the system parameters such as system latency or average turn-on delay without having to modify hardware.

TPS40055EVM-002 operates on the principles of Pulse Width Modulation (PWM) and pulse-by-pulse current mode control. PWM control is used to regulate the voltage at the output of the switch-mode power supplies using digital pulses of varying widths. The duty-cycle of these digital pulses can be adjusted in order to vary the output voltage. At the same time, the signal on the PWM is monitored to ensure the output current remains below the predetermined limits. Pulse-by-pulse current mode control ensures the output current does not exceed the predetermined maximum and therefore the output voltage is not over-driven.

The applications for TPS40055EVM-002 are extensive and include a variety of off-line systems. It is used for controlling non-isolated and isolated DC-DC converters used for powering LEDs, audio amplifiers, mobile phone chargers, drone batteries, and other DC applications. It is also used for powering a variety of AC-DC systems including industrial equipment, computers, consumer electronics, and medical devices.

Specifically, TPS40055EVM-002 can be used for controlling AC-DC forward converters, flyback converters, and low power isolated converters with input voltages ranging from 85 VAC to 265 VAC. Input frequencies range from 44 Hz to 65 Hz. An external circuit is required in order to adapt the input voltage pattern for smooth start-up of the TPS40055EVM-002.

TPS40055EVM-002 also features essential protection features such as thermal protection, open- and short-circuit protection, over-load protection, over-voltage protection, and under-voltage protection. This makes it an ideal choice for end customers who require a reliable and protectable solution.

TPS40055EVM-002 is offered in a multi-board form factor that includes the TPS40055 control IC, various external components, and a push button. Users of this board can quickly customize the output voltage and improve the system\'s behavior by adjusting the system\'s parameters such as output voltage, current limit, open load detection time, and output frequency range. The end user also has the option to use the provided software GUI to configure the system as desired.

Moreover, the TPS40055EVM-002 board contains on-board debug capability that allows users to verify the operation of the device after the system is configured. The board is also in compliance with IEC 61810-1 safety standard, making it suitable for use in a variety of safety systems.

Overall, the TPS40055EVM-002 board is a complete evaluation board that is suitable for a wide range of DC/DC and AC/DC switch-mode power supplies applications. It operates using pulse width modulation and current mode control methods and contains all the essential protection features. It is available in a multi-board form factor with all the necessary configuration parameters, and comes with an on-board debug. It is compliant with the IEC 61810-1 safety standard and therefore suitable for use in a variety of safety systems.
