kr PRODUCT BRIEF LX7167™ 2A Step-Down Converter DESCRIPTION High efficiency, ultra fast transient response regulator for mobile technology and System-OnChip (SOC) processor applications LX7167™ is a step-down PWM switching regulator IC with integrated high side P-Channel and low side N-Channel MOSFETs.
The IC operates using a proprietary hysteretic control topology with a full load operating frequency of 3MHz allowing small output filter components while maintaining excellent dynamic load response.
The operational input voltage range of the LX7167 is from 3V to 5.
5V.
The Power Save Mode (PSM) automatically transitions between PWM and PSM mode depending on the load current.
This allows the converter’s efficiency to remain high when load current drops.
A Power Good function indicates the status of the IC (output voltage level compared to the power good threshold).
In shutdown mode, current consumption is reduced to less than 1uA and the output capacitor is discharged.
