DLynx III™ Master and Satellite DC/DC Converters
OmniOn Power's digital DLynx III power modules are easy to use, highly configurable, non-isolated DC-DC converters that can deliver up to 320 A of output current
OmniOn Power's MLX/SLX series converters operate over a wide input voltage range from 7 VDC to 14 VDC, providing PMBus™ programmable output voltages from 0.45 VDC to 2.0 VDC. DLynx III power modules employ an advanced PID-based adjustable digital control loop that helps ensure loop stability, provides fast transient response, and reduces output capacitance requirements. Up to 160 A of additional SLX series satellite modules can be used with an MLX primary module to increase the maximum output current for a single output or to provide a second independent, digitally controlled output to power multiple loads.
