EVALUATION KIT AVAILABLE  
MAX17548  
42V, Dual-Output, Synchronous  
Step-Down Controller  
General Description  
The MAX17548 is a dual-output, synchronous step-down  
Benefits and Features  
Wide Range of Operation  
controller that drives nMOSFETs.  
• Wide 4.5V to 42V Input Voltage Range  
• Wide 0.8V to 24V Output Voltage Range  
The device features a peak-current-mode, constant-  
frequency architecture, allowing it to operate up to  
2.2MHz. The device can be configured as two single-  
phase, independent 10A power supplies or as a dual-  
phase, single-output 20A power supply. The device also  
provides the ability to run two controllers 180° out-of-  
phase to reduce the power loss and noise due to the  
input-capacitor ESR.  
• R  
or Inductor DCR Current Sensing  
SENSE  
• Selectable In-Phase or 180° Out-of-Phase  
Operation  
• Adjustable 100kHz to 2.2MHz Switching Frequency  
• Independent Enable and PGOOD  
• Available in a Lead(Pb)-Free 32-Pin, 5mm x 5mm  
TQFN-EP Package  
Enhances Power Efficiency  
The IC supports current sensing using either an external  
current-sense resistor for accuracy or an inductor DCR  
for improved system efficiency. Current foldback limits  
MOSFET power dissipation under short-circuit conditions.  
• Low-Impedance Gate Drives for High Efficiency  
• DCM Operation at Light Loads  
• Auxiliary Bootstrap LDO  
Operates Reliably in Adverse Industrial Environments  
• Independent Adjustable Soft-Start or Tracking  
• Current Foldback Limits MOSFET Heat Dissipation  
During a Short-Circuit Condition  
The IC provides independent adjustable soft-start for  
each output and can start up monotonically into a  
prebiased output. The IC can be configured in either  
PWM or DCM modes of operation, depending on whether  
constant-frequency operation or light-load efficiency is  
desired.  
• Operates Over the -40°C to +125°C Temperature  
Range  
• Output Overvoltage and Overtemperature Protections  
The IC operates over the -40°C to +125°C temperature  
range and is available in a lead(Pb)-free, 32-pin TQFN,  
5mm x 5mm package with an exposed pad.  
Ordering Information appears at end of data sheet.
