4.5V Digital Power Management ICs:

37 Products Found

element14's comprehensive selection includes multi-phase controllers, digital POL (point-of-load) converters, and system supervisory ICs from industry-leading manufacturers. These solutions are ideal for servers, data centers, telecommunications equipment, FPGA/ASIC power supplies, and other high-performance applications requiring precise power management.

Digital Power Management ICs (PMICs) represent the latest advancements in power control technology. They make an excellent option for implementing complete power supply solutions. These integrated circuits combine digital processing with power management functions for unprecedented precision and flexibility in power delivery systems. 

With digital interfaces such as  I²C and PMBus, digital PMICs provide real-time monitoring, dynamic voltage adjustment, and precise power sequencing. System efficiency is optimized across varying load conditions while maintaining stable output voltages by incorporating digital control loops and adaptive algorithms. 

Applications span data centre servers and telecommunications equipment to industrial automation and consumer electronics. In high-performance computing, digital PMICs enable complex power sequencing and telemetry, while in portable devices, they maximize battery life through intelligent power distribution.
