Hisiwell has recently launched a quad DC/DC step-down µModule (micromodule) regulator HXM4644 for FPGA control circuits/electronic countermeasures/satellite communication power supply applications, and can Pin to Pin replace ADI (Linear) LTM4644.
* Four channel buck power module
* Wide input voltage range: 4V to 16V
* 0.6V to 5.5V output voltage
* Each channel can provide 4A DC and 5A peak output current
* Typical 1MHz operating frequency
* Support for external frequency synchronization
* Current mode ACOT control, fast transient response
* Parallel current sharing, capable of parallel output of 16A
* Soft start suppression of surge current
* Output voltage tracking function, customized power-on slope
* Internal temperature detection pin
* Protection of over current, over heating, and over voltage
* 77 pin 15mm * 9mm * 5mm BGA package
* Multirail Point of Load Regulation
* FPGAs, DSPs and ASICs Applications
