Description

  • LX7175 SE EVALUATION BOARD, Evaluation Board for the LX7175 is a step-down PWM Switching Regulator IC with integrated high side P-CH and low side N-CH MOSFETs. The IC operates using a hysteretic control topology with a full load switching frequency of 1.4 MHz allowing small output filter components while maintaining excellent dynamic load response. The operational input voltage range of LX7175 is from 3 to 5.5V and it has two modes of operation selected externally by MODE pin. When MODE pin is high, it operates in continuous PWM operation and when it is tied low, it operates in Power Save Mode (PSM) with automatic transition between PWM and PSM mode depending on the load current. This allows the converter efficiency to remain high when load current drops
