EVALUATION KIT AVAILABLE  
MAX16977  
36V, 2A, 2.2MHz Step-Down Converter  
with Low Operating Current  
General Description  
Benefits and Features  
● Supports Up to 2A Loads without External FET  
The MAX16977 is a 2A, current-mode, step-down  
converter with an integrated high-side switch. The device  
is designed to operate with input voltages from 3.5V to  
36V while using only 30FA quiescent current at no load.  
The switching frequency is adjustable from 1MHz to  
2.2MHz by an external resistor and can be synchronized  
to an external clock. The output voltage is pin selectable  
to be 5V fixed or adjustable from 1V to 10V. The wide  
input voltage range along with its ability to operate at  
high duty cycle during undervoltage transients makes the  
device ideal for automotive and industrial applications.  
Saves Space and Cost  
• Integrated 2A Internal High-Side (70mI typ) Switch  
• Fast Load-Transient Response and Current-Mode  
Architecture  
● Direct Car Battery to Sub-5V Rail Conversion at  
Beyond 2MHz Reduces External Component Count  
• 5V Fixed or 1V to 10V Adjustable Output Voltage  
• High Duty Cycle During Undervoltage Transients  
● Robust Input Voltage Up to 36V Supports Automotive  
Applications  
The device operates in skip mode for reduced current  
consumption in light-load applications. Protection features  
include overcurrent limit, overvoltage, and thermal shut-  
down with automatic recovery. The device also features  
a power-good monitor to ease power-supply sequencing.  
• Wide 3.5V to 36V Input Voltage Range  
• 42V Input Transients Tolerance  
• Overvoltage, Undervoltage, Overtemperature, and  
Short-Circuit Protections  
● Meets Tight OEM Power-Consumption Requirements  
The device operates over the -40NC to +125NC automo-  
tive temperature range, and is available in 16-pin TSSOP  
and TQFN (5mm x 5mm) packages with exposed pads.  
with Low I

• 30µA Standby Mode Operating Current  
• 5µA Typical Shutdown Current  
● Advanced Clock Capabilities Offer Further Reduction  
in EMI if Necessary to Enable Noise-Free System
