Microchip Technology, Inc. Voltage Regulators - DC DC Switching Regulators MIC4684-5.0BM TR

The MIC4684-5.0BM TR is a high-efficiency step-down (buck) switching regulator capable of delivering 2A of continuous output current in an 8-lead SO package. It operates at a fixed frequency of 200kHz and achieves power conversion efficiencies exceeding 85%, making it suitable for a variety of applications without the need for an external heat sink. The input voltage range is wide, from 4V to 30V, with a transient tolerance of up to 34V, allowing it to handle input voltage fluctuations effectively. This regulator features built-in safety mechanisms, including over-current protection, frequency-foldback short-circuit protection, and thermal shutdown, ensuring reliable operation under various conditions. The output voltage can be adjusted down to 1.235V, providing flexibility for different application requirements. The MIC4684 is designed for surface mount applications and is rated for operation in ambient temperatures from -40¬8C to +85¬8C, with a junction temperature range of -40¬8C to +125¬8C. Overall, the MIC4684-5.0BM TR is a robust choice for engineers seeking a compact, efficient, and reliable DC-DC voltage regulation solution.
