Automotive 36V, 8A/10A Fully-Integrated  
Buck Converter with 10μA Quiescent  
Current and Dual-Phase Capability  
MAX20408/MAX20410  
General Description  
Benefits and Features  
The MAX20408/MAX20410 are automotive, highly-inte-  
grated synchronous buck converters with internal high-  
side and low-side switches. The ICs deliver up to 8A/10A  
with input voltages from 3.0V to 36V. The voltage quality  
can be monitored by the PGOOD signal. The MAX20408/  
MAX20410 can operate in the dropout mode by running at  
99% duty cycle, making them ideal for automotive and in-  
dustrial applications.  
● High-Power DC/DC Converter in Small Solution Size  
• 3.0V to 36V Operating Input Voltage Range  
• Integrated High-Side and Low-Side FETs  
• 8A/10A Maximum Output Current  
• 400kHz and 2.1MHz Fixed Frequency Options  
• Fixed 2.5ms Soft-Start Time  
• 34ns Minimum On-Time  
• Programmable 0.8V to 10V Output with 400kHz,  
0.8V to 6V Output with 2.1MHz, or Fixed Output  
Options  
The MAX20408/MAX20410 offer programmable or fixed  
output voltage options. High switching frequency at  
2.1MHz and 400kHz options allow for small external com-  
ponents, reduced output ripple, and guarantee no AM  
interference. SYNC input programmability enables three  
modes for optimized performance: forced PWM mode,  
skip mode with ultra-low quiescent current, and synchro-  
nization to an external clock. The spread-spectrum option  
minimizes EMI radiated emissions.  
• ±1.8% Output Voltage Accuracy  
• Symmetric and Balanced SUP and PGND Pinout  
Placement for Superior EMI Performance  
• Thermally-Enhanced 3.5mm x 3.75mm, 17-Pin  
FC2QFN Package  
● High Efficiency at All Load Ranges  
• 10μA Quiescent Current in Skip Mode  
• Up to 94.3% Efficiency at 12V /5V  
/2.1MHz  
/400kHz

The MAX20408/MAX20410 also come with dual-phase  
capability, allowing up to 20A designs. Two ICs can be  
configured as a master and slave with dynamic current  
sharing and 180º out-of-phase operation.  
• Up to 95.6% Efficiency at 12V /5V  
IN  
● Dual-Phase Operation up to 20A Load Capability  
• Frequency Synchronization Input/Output  
• 180º Out-of-Phase Between Master and Slave  
• Dynamic Current Sharing  
The MAX20408/MAX20410 are available in a small  
3.5mm x 3.75mm, 17-pin FC2QFN package. They are  
pin-to-pin compatible with the MAX20404/MAX20405/  
MAX20406 (4A to 6A) family of products.  
● Robust for Automotive Environment  
• Forced PWM and Skip-Mode Operation  
• 99% Duty Cycle Operation with Low Dropout  
Voltage  
Applications
