The LMR14050QDPREVM is an evaluation board specifically designed for DC/DC and AC/DC (Off-Line) SMPS applications. It offers higher efficiency, higher power density and excellent reliability for a wide variety of DC/DC and AC/DC applications.

The board includes two sections. The first provides isolated power output, while the second gives additional power and control functions.

The DC/DC section uses a novel buck-boost switching topology referred as ‘Hybrid DC-DC’. This topology combines the principles of buck-boost with two independent regulators to provide a superior solution compared to conventional synchronous rectification techniques. The AC/DC section uses a full-bridge, non-isolated topology. Both have excellent efficiency at low line and full load conditions.

The LMR14050QDPREVM utilizes a single stage, double isolated architecture to minimize the size and increase efficiency. It includes a pair of isolated DC/DC output stages for operation form 0.6V to 5.5V and 0.9V to 3.6V. The AC/DC section supports input voltages from 12 to 24V and includes an adjustable output from 12V to 24V.

The LMR14050QDPREVM offers a wide range of protections. These include over temperature, over current, short circuit, in-rush current and open loop protection. It also features a built-in fault reporting system and current monitoring. This helps to make the board extremely reliable in all types of applications.

The board also includes a fully integrated control section. This section offers multiple control functions including pulse width modulation (PWM), pulse frequency modulation (PFM) and digital control. It also features a PLL system to provide accurate synchronization with other boards.

The LMR14050QDPREVM is a great choice for DC/DC and AC/DC power systems. It offers a high level of efficiency and reliability, with a wide range of protections to make it suitable for a variety of applications. Its integrated control section and high power density make it ideal for applications such as solar power systems, telecommunications, and consumer electronics.
