MAX17575  
4.5V–60V, 1.5A, High-Efficiency,  
Synchronous Step-Down DC-DC Converter  
with Internal Compensation  
General Description  
Benefits and Features  
Reduces External Components and Total Cost  
The MAX17575 high-efficiency, high-voltage, synchronous  
step-down DC-DC converter with integrated MOSFETs  
operates over a 4.5V to 60V input. The converter can  
deliver up to 1.5A and generates output voltages from  
• No Schottky-Synchronous Operation  
• Internal Compensation for Any Output Voltage  
• All-Ceramic Capacitors, Compact Layout  
0.9V up to 0.9 x V . The feedback (FB) voltage is accu-  
IN  
Reduces Number of DC-DC Regulators to Stock  
rate to within ±1.2% over -40°C to +125°C. Built-in com-  
pensation across the output-voltage range eliminates the  
need for external components. The MAX17575 features  
peak-current-mode control architecture and operates  
in fixed frequency forced PWM mode. The MAX17575  
offers a low minimum on-time that allows high switching  
frequencies and a smaller solution size.  
• Wide 4.5V to 60V Input  
• Adjustable 0.9V to 0.9 × V Output  
• Continuous 1.5A Current Over Temperature  
• 400kHz to 2.2MHz Adjustable Switching Frequency  
with External Synchronization  
IN  
Reduces Power Dissipation  
Peak Efficiency of 94%  
The device is available in a 12-pin (3mm × 3mm) TDFN  
package. Simulation models are available.  
Auxiliary Bootstrap LDO for Improved Efficiency  
• 4.65µA Shutdown Current  
Operates Reliably in Adverse Industrial Environments  
• Hiccup Mode Overload Protection  
• Adjustable Soft-Start  
Applications  
Industrial Control Power Supplies  
General-Purpose Point-of-Load  
Distributed Supply Regulation  
Base Station Power Supplies  
Wall Transformer Regulation  
High-Voltage, Single-Board Systems  
• Built-In Output-Voltage Monitoring with RESET  
• Programmable EN/UVLO Threshold  
• Monotonic Startup into Prebiased Load  
• Overtemperature Protection  
• High Industrial -40°C to +125°C Ambient Operating  
Temperature Range/-40°C to +150°C Junction
