The MP4056GS-Z from Monolithic Power Systems (MPS) is a high-performance primary-side regulated (PSR) LED driver IC designed for cost-effective and reliable LED lighting applications. It integrates a high-voltage startup circuit and power switch, simplifying offline LED driver designs by eliminating the need for optocouplers and secondary-side feedback components.
The device supports flyback converter topologies and provides accurate LED current regulation through primary-side control technology. By sensing the transformer primary-side information, the MP4056GS-Z achieves stable LED output current without requiring additional feedback components, reducing system cost and improving reliability.
MP4056GS-Z is designed for 85VAC to 277VAC input applications and supports a wide range of LED lighting products. The integrated protection functions include LED open-circuit protection, LED short-circuit protection, over-temperature protection, VCC over-voltage protection, and cycle-by-cycle current limiting, enhancing system safety and durability.
The device is supplied in a compact SOIC-8 surface-mount package, making it suitable for space-saving lighting solutions. Typical applications include LED bulbs, LED tubes, downlights, decorative lighting, and other offline LED illumination systems.
