Monolithic Power Systems (MPS) EVQ1923-RE-00A Evaluation Board

Monolithic Power Systems (MPS) EVQ1923-RE-00A Evaluation Board is designed to evaluate and demonstrate the MPQ1923, a high-frequency half-bridge gate driver. This board features a 5V to 17V driver power supply voltage range and Undervoltage-Lockout (UVLO) protection for the High-Side (HS-FET) and Low-Side (LS)-FET gate drivers. The MPQ1923 is available in a small QFN-10 (4mm x 4mm) or QFN-8 (4mm x 4mm) package. Typical applications include telecommunication half-bridge power supplies, avionics DC/DC converters, two-switch forward converters, and active-clamp forward converters.
