The LP8758 is designed to meet the power management requirements of the latest application processors in mobile phones and similar portable applications. The device contains four step-down DC/DC converter cores, which are bundled together in a single 4-phase buck converter. The device is controlled by an I2C-compatible serial interface.
The automatic PWM-PFM (AUTO mode) operation, together with the automatic phase adding/shedding, maximizes efficiency over a wide output-current range. The LP8758 supports remote differential voltage sensing to compensate IR drop between the regulator output and the point-of-load, thus improving the accuracy of the output voltage.
The LP8758 supports programmable start-up and shutdown delays synchronized to Enable signal.
The protection features include short-circuit protection, current limits, input supply UVLO, and temperature warning and shutdown functions. Several error flags are provided for status information of the device. In addition, the LP8758 device supports load current measurement without the addition of external current sense resistors. During start-up and voltage change, the device controls the output slew rate to minimize output voltage overshoot and the inrush current.
