EVALUATION KIT AVAILABLE  
MAX16909  
36V, 220kHz to 1MHz Step-Down Converter  
with Low Operating Current  
General Description  
Features  
The MAX16909 is a 3A, current-mode, step-down con-  
verter 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 220kHz to 1MHz  
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 make the device  
ideal for automotive and industrial applications.  
S Wide 3.5V to 36V Input Voltage Range  
S 42V Input Transients Tolerance  
S High Duty Cycle During Undervoltage Transients  
S 5V Fixed or 1V to 10V Adjustable Output Voltage  
S Integrated 3A Internal High-Side (70mI typ)  
Switch  
S Fast Load-Transient Response and Current-Mode  
Architecture  
S Adjustable Switching Frequency (220kHz to 1MHz)  
S Frequency Synchronization Input  
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.  
S 30µA Standby Mode Operating Current  
S 5µA Typical Shutdown Current  
S Overvoltage, Undervoltage, Overtemperature, and  
Short-Circuit Protections  
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.
