The LP8758-E0 device is designed to meet power management requirements for low-power processors in mobile phones, network cards, and similar applications. The device contains four step-down DC-DC converter cores, providing four output voltage rails. The device is controlled by an I2C-compatible serial interface.

The automatic PWM-PFM (AUTO mode) operation maximizes efficiency over a wide output-current range.

The LP8758-E0 supports programmable start-up and shutdown sequencing synchronized to hardware Enable input 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-E0 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.
