MPQ8634B

16V, 20A, Sync, Step-Down Converter

with Adjustable Current Limit,

Programmable Frequency, and Voltage Tracking

The Future of Analog IC Technology



20A 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

Selectable Pulse-Skip Mode or Forced CCM

Operation

The MPQ8634B is a fully integrated, high-

frequency, synchronous, buck converter. The

MPQ8634B offers a very compact solution that

achieves up to 20A output current with excellent

load and line regulation over a wide input

supply range. The MPQ8634B operates at high

efficiency over a wide output current load range.



The

MPQ8634B

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

configuration, allowing the MPQ8634B’s

frequency to remain constant regardless of the

input/output voltages.



Excellent Load Regulation

Output Voltage Tracking

Output Voltage Discharge

PGOOD Actively Clamped at a Low Level

during Power Failure



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 MPQ8634B.

Selectable Switching Frequency from

600kHz, 800kHz, and 1000kHz

Non-Latch 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 MPQ8634B 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
