Quad 3A, Ultrathin µModule Regulator Fits on the Backside of PCB
The LTM4643 is a quad output step-down µModule® (power module) regulator, configurable as a single output (12A), dual (6A & 6A or 9A & 3A), or quad (3A each) regulator in a 9mm × 15mm × 1.82mm ultrathin LGA package. This flexibility enables system designers to rely on one simple and compact µModule regulator for a variety of voltage and load current requirements in FPGA, GPU, ASIC and processor-based applications. The 1.82mm height ultrathin package allows the LTM4643 to be mounted on the backside of the PCB, freeing space on the topside for components such as memory and connectors. The LTM4643 is suitable for systems with height restrictions, such as backside PCB assembly in PCIe applications and where the regulator must fit under a common heat sink or cold plate to cool high power FPGAs, GPUs, ASICs and processors in applications such as embedded computing, data storage, medical imaging and industrial systems.
