MP8860

2.8 - 22V V_IN, 1A I_OUT, 4-Switch,

Integrated Buck-Boost Converter

with I²C Interface

DESCRIPTION

FEATURES



Wide 2.8V to 22V Operating Input Voltage

Range

The MP8860 is a synchronous, 4-switch,

integrated buck-boost converter capable of

regulating the output voltage from a 2.8V to 22V

wide input voltage range with high efficiency.



1V ⁽¹⁾to 20.47V Output Voltage Range (5V

Default) with 10mV Resolution through I²C

1A Output Current or 4A Input Current

Four Low R_DS(ON)Internal Buck Power

MOSFETs



The MP8860 uses constant-on-time (COT)

control in buck mode and constant-off-time

control in boost mode, providing fast load

transient response and smooth buck-boost

mode transient. The MP8860 provides auto

PFM/PWM or forced PWM switching modes,

and programmable output constant current (CC)

current limit, which supports flexible design for

different applications.



Adjustable Accurate CC Output Current

Limit with Internal Sensing MOSFET via I²C

500kHz Switching Frequency

Output Over-Voltage Protection (OVP)

Hiccup



Output Short-Circuit Protection (SCP) with

Hiccup

Full protection features include over-current

protection (OCP), over-voltage protection



Over-Temperature Warning and Shutdown

I²C Interface with ALT Pin

(OVP),

under-voltage

protection

(UVP),

Four Programmable I²C Addresses

One-Time Programmable (OTP) Non-

Volatile Memory

programmable soft start, and thermal shutdown.

The MP8860 is available in a 16-pin QFN

(3mmx3mm) package.



I²C Programmable Line Drop Compensation,

PFM/PWM Mode, Soft Start, OCP, etc.

EN Shutdown Discharge Programmable

Available in a QFN-16 (3mmx3mm)

Package



APPLICATIONS



Power Supply for Motor

Buck-Boost Bus Supplies



Industrial Systems

Personal Medical Products

DSLR Cameras
