MPQ8634A

16V, 12A, Sync, Step-Down Converter

with Adjustable Current Limit,

Programmable Frequency, and Voltage Tracking

The Future of Analog IC Technology



12A Output Current

DESCRIPTION

Low R_DS(ON)Integrated Power MOSFETs

Proprietary Switching Loss Reduction

Technique

Adaptive COT for Ultrafast Transient

Response

Stable with Zero ESR Output Capacitor

0.5% Reference Voltage over 0°C to

+70°C Junction Temperature Range

1% Reference Voltage from -40°C to

+125°C Junction Temperature Range

Pin-Selectable Pulse-Skip Mode or Forced

CCM Operation

The MPQ8634A is a fully integrated, high-

frequency, synchronous, buck converter. The

MPQ8634A offers a very compact solution that

achieves up to 12A output current with excellent

load and line regulation over a wide input

supply range. The MPQ8634A operates at high

efficiency over a wide output current load range.



The

MPQ8634A

adopts

internally



compensated constant-on-time (COT) control

mode that provides fast transient response and

eases loop stabilization.

The operating frequency can be set to 600kHz,

800kHz, or 1000kHz easily with MODE



Excellent Load Regulation

Output Voltage Tracking

Output Voltage Discharge

PGOOD Actively Clamped at a Low Level

during Power Failure

configuration,

allowing

the

MPQ8634A

frequency to remain constant regardless of the

input/output voltages.



Programmable Soft-Start Time from 1.5ms

Pre-Bias Start-Up

The output voltage start-up ramp is controlled

by an internal 1.5ms timer. It can be increased

by adding a capacitor on TRK/REF. An open-

drain power good (PGOOD) signal indicates

when the output is within its nominal voltage

range. PGOOD is clamped at around 0.7V with

an external pull-up voltage when the input

supply fails to power the MPQ8634A.

Selectable Switching Frequency from

600kHz, 800kHz, and 1000kHz

Latch-Off OCP, UVP, UVLO, Thermal

Shutdown, and Latch-Off for OVP

Output Adjustable from 0.9V to 90%*VIN,

up to 6V Max



Available in

Package

QFN-21 (3mmx4mm)

Fully integrated protection features include

over-current protection (OCP), over-voltage

protection (OVP), under-voltage protection

(UVP), and over-temperature protection (OTP).

APPLICATIONS



Telecom and Networking Systems

Servers, Cloud-Computing, Storage

Base Stations

The MPQ8634A requires a minimal number of

readily

available,

standard,

external

components and is available in a QFN-21

(3mmx4mm) package.



General Purpose Point-of-Load (PoL)

12V Distribution Power Systems

High-end TV

FEATURES



Wide Input Voltage Range:

o 2.85V to 16V with External 3.3V VCC

Bias
