Overview
| The LX7178 is a digitally controlled step-down regulator IC with integrated high side P-Ch and low side N-CH MOSFETs, an I2C serial interface port, a hysteretic control engine, and fault monitoring functions. The fast transient response of constant frequency hysteretic control allows for minimal filter components. At low output currents, the switching frequency is lowered (PSM = Power Saving Mode) to optimize light load efficiency and extend battery life in mobile applications. The LX7178 will operate from 5v or 3.3v rails. The bi-directional, high speed I2C serial interface allows for on-the-fly output voltage margining and monitoring. Cycle-by-cycle current limiting protects the regulator against over-current conditions. The LX7178 operates in hiccup mode to further enhance the robustness of the converter for heavy over-load or short-circuit faults and it automatically recovers once the fault clears. Thermal protection shuts down the regulator under an over-temperature condition. The LX7178 is identical to the LX7165, other than its startup mode. The LX7178 defaults in PSM mode. |
