Product Description
The JW5033C is a current-mode monolithic buck voltage converter designed for efficient power regulation. It operates with an input voltage range of 4.5V to 18V and delivers up to 2A of continuous output current. The device integrates two N-Channel MOSFETs and operates in low frequency at light loads to maintain high efficiency and minimize output ripple. Key features include short circuit protection, thermal protection, current run-away protection, and input under-voltage lockout, ensuring robust performance. Its compact SOT23-6 package requires minimal external components, making it suitable for space-constrained applications.
The JW5033C is ideal for various applications including Distributed Power Systems, Networking Systems, FPGA, DSP, ASIC Power Supplies, Green Electronics/Appliances, and Notebook Computers.
