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)
