MP8869W

3V - 18V, 12A, High-Efficiency, Wide-Input,

Synchronous Step-Down Converter with

Integrated Telemetry via I²C Interface

FEATURES

DESCRIPTION



Wide 3V to 18V Operating Input Range

12A Continuous/15A Peak Output Current

1% Internal Reference Accuracy

I²C Programmable Output Range from 0.6V

to 1.55V in 7.5mV Steps with Slew Rate

Control

The

MP8869W

high-frequency,

synchronous, rectified, step-down, switch-mode

converter with an I²C control interface. It offers a

fully integrated solution that achieves 12A of

continuous and 15A of peak output current with

excellent load and line regulation over a wide

input supply range.

In the I²C control loop, the output voltage level

can be controlled on-the-fly through an I²C serial

interface. The voltage range can be adjusted

from 0.6V to 1.55V in 7.5mV steps. Voltage slew

rate, frequency, current limit, hiccup/latch-off

protection, enable, and power saving mode are

also selectable through the I²C interface.



5% Accuracy Output Voltage and Output

Current Monitoring via I²C

Selectable PFM/PWM Mode, Adjustable

Frequency and Current Limit through I²C

4 Different Selectable I²C Addresses

External Soft Start

Open-Drain Power Good Indication

Output Over-Voltage Protection (OVP)

Hiccup/Latch-Off OCP



Constant-on-time (COT) control operation

provides fast transient response. An open-drain

power good (PG) pin indicates that the output

voltage is in the nominal range. Full protection

features include over-voltage protection (OVP),

over-current protection (OCP), and thermal

shutdown.

Available in a QFN-14 (3mmx4mm)

Package

APPLICATIONS



Solid-State Drive (SSD)

Flat-Panel Television and Monitors

Digital Set-Top Boxes

Distributed Power Systems

Networking/Server

The MP8869W is available in a QFN-14

(3mmx4mm) package.
