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.
