The LM2700MT-ADJEV is a highly-versatile switching regulator power supply that is suitable for a wide range of applications. It is based on the LM3507 dual-channel current-mode control DC/DC synchronous buck and flyback controller, and supports input voltage independent of up to 350V and output voltage up to 100V. Furthermore, the LM2700MT-ADJEV is optimized for maximum efficiency and has plenty of features including adjustable fixed-frequency operation, one-cycle skip mode, active current insert, line undervoltage protection, and remote on/off control. Thanks to its low output ripple noise, fast transient response, and flexible programming capabilities, the LM2700MT-ADJEV is an ideal choice for powering industrial, communications, and medical equipment.

The LM2700MT-ADJEV belongs to the Evaluation Boards - DC/DC & AC/DC, or Off-Line, SMPS category. This category provides designers produts of SMPS that are particularly suitable for offline applications. It includes highly advanced products for AC/DC and DC/DC applications, ranging from universal AC input off-line applications to complex multichannel off-line applications. The LM2700MT-ADJEV falls mostly under the DC/DC type, as its controller is a dual-channel current-mode control DC/DC synchronous buck and flyback controller for outputs up to 100V.

The working principle behind the LM2700MT-ADJEV is simple yet efficient. At first, the controller senses the current in the output transformer with the included PrimarySense circuitry, and then adjusts the switching of the power MOSFETs accordingly. The device includes two current sense amplifiers that adjust the amount of current entering into the primary and secondary sides of the transformer. Based on the amount of current the controller senses, it adjusts the switching of the MOSFETs to maintain a constant current flow.

The LM2700MT-ADJEV also includes other features that improve the system’s efficiency and reduce the operating cost. This includes a power good signal that indicates when the output voltage is stable, auto-restart functionality, adjustable soft start, and frequency jitter technology which helps reduce electromagnetic interference (EMI). Furthermore, the device also supports wide input voltage range for both buck and flyback operations, making it suitable for a variety of applications.

In conclusion, the LM2700MT-ADJEV is a highly versatile and reliable switching regulator power supply. It offers adjustable fixed-frequency operation, a wide input and output voltage range, low output ripple noise, fast transient response, and flexible programming capabilities. The device’s working principle is based on the LM3507 dual-channel current-mode control DC/DC synchronous buck and flyback controller, and also includes other features that improve the system’s efficiency and reduce the operating cost. Thanks to its features, the LM2700MT-ADJEV is an ideal choice for powering industrial, communications, and medical equipment.
