DC2119A

The DC2119A Evaluation Board from Linear Technology is a highly sophisticated and versatile tool that can be used to evaluate and test low-noise AC/DC and DC/DC switching power supplies and other circuits. The DC2119A provides an easy-to-use evaluation board, along with its accompanying software, for testing and evaluating the performance of power supplies.

The main application field of the DC2119A is in laboratory and research settings, where it can easily test and evaluate different types of power supply circuits and parameters. This makes it extremely useful in helping engineers learn and understand complex power supply circuits.

The DC2119A is able to measure and evaluate the performance of AC/DC and DC/DC switching power supplies. It can also be used to measure the AC/DC ripple generated from switching power supplies. Additionally, the evaluation board can measure DC voltages, current, and switching power losses. It can also monitor the transient response of a power supply, including frequency-response measurements, power-factor-corrected peak-current measurements, and dynamic load regulation measurements. Additionally, the DC2119A can measure AC drain-to-source capacitances and AC switching losses on mosfet switches.

The DC2119A has 8 isolated channels to measure the AC/DC and DC/DC current waveforms of a power supply. The channels are split into 6 differential inputs and 2 singleended inputs. The differential input is used to measure the current through a switching device, while the single-ended input is used to measure the voltage across a resistive device. The evaluation board is also capable of measuring the voltage and current waveforms of a power supply circuit.

The working principle of the DC2119A is based on a switching power supply circuit. The board includes two sets of feedback circuitry – one for the output stage and the other for the input stage. The output stage is based on a flyback topology, while the input stage uses an H-bridge configuration. When the board is powered on, the switch mode power supply (SMPS) will generate a fixed voltage and applies it to the voltage feedback circuit. This voltage is used to compare the actual voltage output of the SMPS and adjust the duty cycle of the output stage accordingly.

The SMPS also includes several safety features that help ensure the power supply does not become overloaded or overheat. The power supply also contains a low current shutoff that prevents damage to the power supply or any connected devices. Additionally, the board includes power-on-reset circuitry that monitors for any voltage drop and resets the power supply if necessary.

Overall, the DC2119A Evaluation Board from Linear Technology is a powerful tool for testing and evaluating AC/DC and DC/DC switching power supplies. It provides a convenient platform to measure and evaluate various parameters from a power supply circuit. Additionally, the board provides several safety features that help ensure that the power supply does not become overloaded or overheat.
