EVALUATION KIT AVAILABLE  
MAX17290/MAX17292  
2.5V to 36V, 2.5MHz, PWM Boost Controller  
with 4µA Shutdown Current and Reduced EMI  
General Description  
Benefits and Features  
● Reduces Solution Size and Cost  
• All-Ceramic Capacitor Solution Allows Ultra-Compact  
Solution Size  
The MAX17290/MAX17292 high-efficiency, synchronous  
step-up DC-DC controllers operate over a 4.5V to 36V  
input voltage range with 42V input transient protection.  
The input operating range can be extended to as low as  
2.5V in Bootstrapped mode.  
• 100kHz to 1MHz (MAX17290) and 1MHz to  
2.5MHz (MAX17292) Switching-Frequency with  
External Synchronization  
The MAX17290 and MAX17292 use a constant-frequency,  
pulse-width modulating (PWM), peak current-mode  
control architecture. There are multiple versions of the  
devices offering one or more of the following functions:  
a synchronization output (SYNCO) for 180° out-of-phase  
operation, an overvoltage protection function using a  
separate input pin (OVP), and a reference input pin  
(REFIN) to allow on-the-fly output voltage adjustment.  
● Increases Design Flexibility  
• Bootstrapped Mode Allows Input Voltage to be 2.5V  
• Adjustable Slope Compensation  
● Reduces Power Dissipation  
• >90% Peak Efficiency  
• Low 4μA (typ.) Shutdown Current  
● Operates Reliably  
The MAX17290 and MAX17292 operate in different  
frequency ranges. All versions can be synchronized to an  
external master clock using the FSET/SYNC input.  
• 42V Input Voltage Transient Protection  
• Fixed 9ms Internal Software Start Reduces Input  
Inrush Current  
• PGOOD Output and Hiccup Mode for Enhanced  
System Protection  
• Overtemperature Shutdown  
• Reduced EMI Emission with Spread-Spectrum  
Control  
The devices are available in a compact 12-pin (3mm x  
3mm) TQFN and 10-pin µMAX packages. Both packages  
have exposed pads. -40°C to +85°C Operation.
