1.5MHz Dual 180° Out-of-Phase

PWM Step-Down Controller with POR

General Description

Features

The MAX8529 dual, synchronized, step-down controller

generates two outputs from input supplies ranging from

4.75V to 23V. Each output is adjustable from sub-1V

to 18V. Input voltage ripple and total RMS input ripple

current are reduced by synchronized 180-degree out-of-

phase operation.

♦ Low Output Noise in DSL Band

♦ Ceramic Input/Output Capacitors

♦ Step-Down or Step-Up/Step-Down Operation

♦ Four Output, 90-Degree Out-of-Phase Operation

(Using Two MAX8529s)

The switching frequency is adjustable from 600kHz to

1.5MHz with an external resistor. Alternatively, the con-

troller can be synchronized to an external clock gener-

ated to another MAX8529 or a system clock. One

MAX8529 can be set to generate an in-phase, or 90-

degree out-of-phase, clock signal for synchronization

with additional controllers. This allows two controllers to

operate either as an interleaved two- or four-phase sys-

tem with each output shifted by 90 degrees. These

devices also feature soft-start and soft-stop.

♦ Foldback Current Limit

♦ 4.75V to 23V Input Supply Range

♦ 0 to 18V Output Voltage Range (Up to 6A)

♦ > 90% Efficiency

♦ Fixed-Frequency PWM Operation

♦ Adjustable 600kHz to 1.5MHz Switching

Frequency

The MAX8529 eliminates the need for current-sense

resistors by utilizing the low-side MOSFET’s on-resis-

tance as a current-sense element. This protects the

DC-to-DC components from damage during output

overload conditions or when output short circuit faults

without requiring a current-sense resistor. Adjustable

foldback current limit reduces power dissipation during

short-circuit conditions. The MAX8529 includes a

power-on reset output to signal the system when both

outputs reach regulation.

♦ External SYNC Input

♦ Clock Output for Master/Slave Synchronization

♦ Soft-Start and Soft-Stop

♦ RST Output with 140ms Minimum Delay

♦ Lossless Current Limit (No Sense Resistor)
