MPQ8655

16V, 30A, Scalable, Digital, Synchronous

Step-Down Converter with PMBus

DESCRIPTION

FEATURES

The MPQ8655 is a fully integrated, PMBus-

compliant, high-frequency, synchronous buck

converter. The MPQ8655 offers a very compact

solution that achieves up to 30A of output

current (I_OUT) per phase, with excellent load and

line regulation across a wide input supply

range. The MPQ8655 operates at high

efficiency across a wide I_OUTload range.

•

PMBus 1.3 Compliant

Scalable Multi-Phase Operation

3.1V to 16V Input Voltage (V_IN) with

External 3.3V V_CCBias

4V to 16V V_INwith Internal Bias

30A Continuous Output Current (I_OUT) per

Phase

Low On Resistance (R_DS(ON)) Integrated

Power MOSFETs

Lossless and Accurate On-Die Current

Sensing

Adaptive Multi-Phase Constant-On-Time

(MCOT) for Ultra-Fast Transient Response

Stable with Zero-ESR Output Capacitors

0.5% Reference Voltage (V_REF) Across 0°C

to 70°C Junction Temperature (T_J) Range

Output Voltage (V_OUT) True Remote Sense

V_OUT, I_OUT, V_IN, and T_JReporting

V_OUTAdjustable from 0.4V to 0.9 x V_IN, Up

to 5.5V Max

Built-In Multiple-Time Programmable (MTP)

Memory to Store Custom Configurations

Configurable via PMBus:

o V_OUT

o I_OUTLimit

o Selectable Pulse-Skip Mode or Forced

Continuous Conduction Mode (FCCM)

o Soft-Start Time (t_SS)

•

The PMBus interface provides converter

configurations and monitors key parameters.

The MPQ8655 adopts MPS’s proprietary multi-

phase constant-on-time (MCOT) control, which

provides fast transient response and eases loop

stabilization. The MCOT scheme also allows

multiple MPQ8655 devices to be connected in

parallel, with excellent current sharing and

phase interleaving for high-current applications.

•

Fully integrated protection features include

over-current protection (OCP), over-voltage

protection (OVP), under-voltage protection

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

•

The MPQ8655 requires a minimal number of

readily available, standard external components,

and is available in a TQFN-25 (4mmx5mm)

package.

o Selectable 400kHz, 600kHz, 800kHz, or

1000kHz Switching Frequency (f_SW)

o OCP, OVP, and OTP with Options for

Hiccup or Latch-Off Mode

o Ramp Compensation
