MPQ8612

High Efficiency, 12A/16A/20A, 6V

Synchronous Step-down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MPQ8612 is fully integrated high frequency

synchronous rectified step-down switch mode

converter. It offers very compact solutions to

achieve 12A/16A/20A output current from a 3V to

6V input with excellent load and line regulation.

•

Wide 3V to 6V Operating Input Range

12A/16A/20A Output Current

Low R_DS(ON) Internal Power MOSFETs

Proprietary Switching Loss Reduction

Technique

•

Adaptive COT for Ultrafast Transient

Response

1% Reference Voltage Over -20°C to

+85°C Junction Temperature Range

Programmable Soft Start Time

Pre-Bias Start up

Programmable Switching Frequency from

300kHz to 1MHz.

Minimum On Time T_{ON_MIN}=60ns

Minimum Off Time T_{OFF_MIN}=75ns

Non-latch OCP, non-latch OVP Protection

and Thermal Shutdown

Constant-On-Time

(COT)

control

mode

provides fast transient response and eases loop

stabilization. The MPQ8612 can operate with a

low-cost electrolytic capacitor and can support

ceramic output capacitor with external slope

compensation.

•

Operating frequency is programmed by an

external resistor and is compensated for

variations in V_IN.

•

Under voltage lockout is internally set at 2.8 V,

but can be increased by programming the

threshold with a resistor network on the enable

pin. The output voltage startup ramp is

controlled by the soft start pin. A power good

signal indicates the output is within its nominal

voltage range.

Output Adjustable from 0.608V to 4.5V

APPLICATIONS

•

Telecom System Base Stations

Networking Systems

Server

Personal Video Recorders

Flat Panel Television and Monitors

Distributed Power Systems

Full fault protection including OCP, SCP, OVP

UVP and OTP is provided by internal

comparators.

The MPQ8612 requires a minimum number of

readily available standard external components

and are available in QFN3X4/4X4/4X4 packages.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Products, Quality Assurance page.
