ADP1871-BL1-EVZ is an evaluation board designed to measure the performance of the ADP1871 flyback controller IC. It is capable of supporting applications with varying output power ratings, making it ideal for custom or universal designs. The board is applicable to both DC/DC and AC/DC (off-line) SMPS with power ranges from 10W to 100W and output voltage from 5V to 48V.

The ADP1871-BL1-EVZ evaluation board is designed to support mains voltage from 90Vac - 265Vac so it can be used in a wide range of global applications. It includes on-board adjustable (external) current limiting that ranges from 0.8A to 5.5A which can satisfy the input power requirements for many applications. It also includes on-board adjustable (external) output voltage adjustment, from 5V to 48V, which helps optimize the output power stability for various output power levels.

The ADP1871-BL1-EVZ provides all the necessary components and protections needed to properly design and test DC/DC and AC/DC (off-line) SMPS applications. The evaluation board is supplied with full design support including circuit diagrams, CAD layouts, schematics, performance data and test results.

The ADP1871-BL1-EVZ evaluation board works on the simple principles of flyback controller ICs. This board is specifically designed with a single switch flyback topology, enabling it to deliver high efficiency in either DC/DC or AC/DC (off-line) applications. When used in DC/DC applications, the board can deliver up to 96%, while in AC/DC applications efficiency can reach up to 85%.

The evaluation board includes a low-cost topology implementable with the ADP1871 flyback controller IC, widely used in cost effective non-isolated applications. The board uses an insulated gate bipolar transistor (IGBT) together with a synchronous rectifier diode with low reverse recovery. This high efficiency, low cost topology offers a viable alternative to cost effective single switch flyback applications.
