Overview
The LTM4615IV#PBF is a highly integrated, triple-output DC/DC power module from Analog Devices. It combines a dual 4A switching mode DC/DC power supply with an additional 1.5A very low dropout (VLDO) linear regulator. This module is part of the uModule family and is designed for low-voltage applications, offering a compact and efficient power solution.
The module includes all necessary components such as switching controllers, power FETs, inductors, and support components, making it a complete power management solution. It is housed in a thermally enhanced 144-lead LGA package, measuring 15mm x 15mm x 2.82mm, which is ideal for high-density point-of-load regulation.
