3 Description
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.
