Overview
The LTM4615IV#PBF, produced by Analog Devices Inc., is a high-efficiency, high-density DC/DC power module. It integrates a 4A dual output switching mode DC/DC power supply along with an additional 1.5A very low dropout (VLDO) linear regulator. This µModule regulator is designed for high-density point-of-load regulation and features a compact 15mm × 15mm × 2.82mm LGA package, making it ideal for space-constrained applications. The device supports a wide input voltage range, high switching frequency, and current mode architecture, ensuring fast transient response and stability. It also includes various protection features such as overvoltage, overcurrent, and thermal shutdown, as well as programmable soft-start and output voltage tracking capabilities.
