Specialized Power Modules

High Output Voltage Power Modules

The LMZ1420xH SIMPLE SWITCHER power modules have an output voltage range from 5V to 30V. These power modules are ideal for intermediate rail conversions, powering fans or other types of non-traditional points of load, and for sensing applications requiring voltages below -6V.

Extended Temperature (EXT) Family of Power Modules

The SIMPLE SWITCHER EXT power modules provide excellent performance in the most extreme conditions, with extended ambient temperatures guaranteed down to -55° C and shock and vibration compliant to meet military MIL-STD-883 standards.

LMZ2-Series Power Modules

The LMZ2-series power modules (LMZ2xxxx) are available in output currents up to 10A with additional features for powering high current intermediate rails, FPGAs, and noise sensitive applications. They also feature a frequency synchronization pin that controls the switching frequency of the internal circuitry, and a current sharing pin for paralleling multiple power modules together for achieving up to 60A of output current.

Frequency Synchronization

  • Optimize efficiency and control switching noise in noise-sensitive systems with the power module's synchronizable switching frequency.
  • Synchronization pin can be set to a certain frequency for ease of filtering.
  • Multiple power modules can operate at the same frequency or phase shifted to reduce input RMS current and ripple voltage.

Current Sharing

Parallel multiple modules for up to 60A of output current in high-current intermediate rail and FPGA applications.
