LTM4644IY Description

Short technical summary and product information.

The LTM4644IY is a quad DC/DC step-down µModule (micromodule) regulator from Analog Devices Inc./Maxim Integrated. It delivers 4A continuous (5A peak) output current per channel, with outputs that can be paralleled for up to 16A capability. The module integrates switching controllers, power FETs, inductors, and support components in a compact 77-BBGA package measuring 15.0mm x 9.0mm x 5.01mm.

 

Operating over an input voltage range of 4V to 14V (or 2.375V to 14V with an external bias supply), the LTM4644IY supports output voltages from 0.6V to 5.5V. It features current mode control for fast transient response, output voltage tracking, external frequency synchronization, and an internal temperature sensing diode. Protection features include overcurrent, overtemperature, and overvoltage protection.

 

This surface-mount module is designed for multirail point-of-load regulation in applications such as FPGAs, DSPs, and ASICs. Only bulk input and output capacitors are needed for operation. The device is rated for an operating temperature range of -40°C to 125°C.
