MPQ8616

High Efficiency, 6A/12A, 6V

Synchronous Step-down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MPQ8616 is fully integrated high frequency

synchronous rectified step-down switch mode

converter. It offers very compact solutions to

achieve 6A/12A output current from a 3V to 6V

input with excellent load and line regulation.

•

Wide 3V to 6V Operating Input Range

6A/12A Output Current

Low R_DS(ON) Internal Power MOSFETs

Proprietary

Technique

Switching

Loss

Reduction

•

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}=100ns

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 MPQ8616 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. It is almost constant with all the

input voltage and output load conditions.

•

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 0.61V 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 MPQ8616 requires a minimum number of

readily available standard external components and

are available in QFN3x4 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.
