MP8867

High-Efficiency, 8A, 17V, Synchronous

Step-Down Converter with I²C Interface

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP8867 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter

with an I²C control interface. It achieves an 8A

output current with excellent load and line

regulation over a wide input supply range.



Wide 4.5V to 17V Operating Input Range

1% Internal Reference Accuracy

I²C Programmable Reference Output

Voltage



Reference Voltage Range from 0.6V to

1.87V in 10mV Steps with Slew Rate

Control

The reference voltage level is controlled by the

I²C serial interface with an adjustable reference

voltage ranging from 0.6V to 1.87V in 10mV

steps. The voltage scaling slew rate, the

switching frequency, enable/sync, and power

save mode are all selectable through the I₂C

interface.



I²C Selectable Switching Frequency

200kHz to 2MHz Synchronized External

Clock



OTP and OCP Hiccup Indication via I²C

Selectable PSM and FS through I²C

Programmable Soft-Start Time

Open-Drain Power Good Indicator

Small 3x4mm QFN-14 Package

Current-mode operation provides

transient response and eases loop stabilization.

EN/SYNC supports external clock

fast

synchronization, and an open-drain power good

indicates when the output voltage is in the

nominal range. Full protection features include

over-voltage protection (OVP), hiccup over-

current protection (OCP), and thermal

shutdown.

APPLICATIONS



FPGA-Based Systems

ASIC Supplies
