DC DC CONVERTER 4X0.6-5.5V
Analog Devices LTM4644IY#PBF is a quad step-down DC/DC µModule® power module integrating switching controllers, power MOSFETs, inductors, and support components for compact multi-rail point-of-load power conversion. It supports four independently configurable outputs with up to 4A continuous current per channel and is suitable for FPGA, DSP, ASIC, and other space-constrained power applications.
Performance：LTM4644IY#PBF operates from a 4V to 14V input range, or 2.375V to 14V with external bias, and provides programmable output voltages from 0.6V to 5.5V. Each channel supports 4A DC and 5A peak output current, with ±1.5% total output voltage regulation and fast transient response. Outputs can also be paralleled for higher-current configurations up to 16A.
Features：LTM4644IY#PBF integrates a current-mode control architecture with output voltage tracking, external frequency synchronization, internal temperature sensing, and overvoltage, overcurrent, and overtemperature protection. Its highly integrated design requires only a small number of external input and output capacitors, simplifying PCB power-supply implementation.
Package & Applications：LTM4644IY#PBF is specified by Analog Devices as a 77-lead BGA package measuring 9mm × 15mm × 5.01mm; the provided BGA-104 designation does not match the manufacturer’s current package listing. It is designed for multi-rail point-of-load regulation and power delivery in FPGAs, DSPs, ASICs, and other compact electronic systems.
