The LP8754 is designed to meet the power management requirements of the latest applications processors in mobile phones and similar portable applications. The device contains six step-down DC/DC converter cores, which are bundled together in a 6-phase buck converter. The device is fully controlled by a Dynamic Voltage Scaling (DVS) interface or an I2C-compatible serial interface.

The automatic PWM/PFM operation together with the automatic phase adding/shedding maximizes efficiency over a wide output current range. The LP8754 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 protection features include short-circuit protection, current limits, input OVP, UVLO, temperature warning, and shutdown functions. Several error flags are provided for status information of the IC. In addition, I2C read-back includes total load current and load current for each buck core: The LP8754 has the ability to sense current being delivered to the load without the addition of current sense resistors. During start-up, the device controls the output voltage slew rate to minimize overshoot and the inrush current.

For all available packages, see the orderable addendum at the end of the datasheet.
