TPS54229EEVM-056 Evaluation Board is a necessity when designing on-board DC/DC & AC/DC (Off-Line) Switch Mode Power Supplies (SMPS). It sports high efficiency and low quiescent current consumption, while offering peak output current and load transient performance.The TPS54229EEVM-056 Evaluation Board is based on the TPS54229 high-performance low-input DC/DC converter with 1.5 A peak current-limit, low externally adjustable output voltage, low quiescent current and high efficiency. The board features secondary-side output voltage adjustment with an integrated reference voltage and a precision power MOSFET, as well as a low-power standby operation capability. The TPS54229EEVM-056 can also be used to evaluate a wide range of TPS54229-compatible products. Basic features of the TPS54229EEVM-056 Evaluation Board include the following:- Wide input voltage range (6 V to 42 V)- Over-voltage protection- Precision reference voltage- Adjustable output voltage range from 0.5 V to 5.5 V- Efficient 2 A synchronous step-down DC/DC converter with 1.5 A peak current limit- Peak load transient performance up to 4 A- Low quiescent current and low output voltage ripple- Soft-start of output voltage- Power-save mode compliant- Thermal shutdown protection- Short-circuit protectionThe overall working principle of the TPS54229EEVM-056 consists of several parts. First, the input voltage is conditioned by the input supply circuitry. Once set, this input voltage is passed to the switching regulator, which then regulates the output voltage according to the reference voltage applied externally. To achieve this, a precision voltage reference is included inside the power switch which can adjust the output voltage from 0.5 V to 5.5 V. A low-power standby mode is also provided to reduce the quiescent current, should the application require it.Through the switching regulator, the TPS54229EEVM-056 board is capable of generating an output current of up to 2 A in constant voltage regulation. This output current is determined by the peak current limit set externally, which can be up to 1.5 A. During load transients of up to 4 A, the board is capable of providing maximum efficiency and reliability.The TPS54229EEVM-056 can also support a soft-start function, allowing the output voltage to slowly ramp up upon power up. Additionally, the board is includes a variety of protection features such as short-circuit protection, over-voltage protection, output current limit and thermal shutdown protection.In summary, the TPS54229EEVM-056 Evaluation Board is an essential component for designing high-performance, cost-effective DC/DC & AC/DC (Off-Line) SMPS. Its wide input voltage range, precision reference voltage, high efficiency, low quiescent current and load transient performance ensure reliable operation even in extreme conditions. The board includes a variety of protection features and feature a low-power standby mode.
