MAX16904  
2.1MHz, High-Voltage,  
600mA Mini-Buck Converter  
General Description  
Features  
Wide +3.5V to +28V Input Voltage Range  
The MAX16904 is a small, synchronous buck converter  
with integrated high-side and low-side switches. The  
device is designed to deliver 600mA with input voltages  
from +3.5V to +28V while using only 25μA quiescent  
current at no load. Voltage quality can be monitored  
by observing the PGOOD signal. The MAX16904 can  
operate in dropout by running at 97% duty cycle, making  
it ideal for automotive and industrial applications.  
Tolerates Input Voltage Transients to +42V  
600mA Minimum Output Current with Overcurrent  
Protection  
Fixed Output Voltages (See the Selector Guide and  
Contact Factory for All Available Trimmed Output  
Voltage Options)  
● 2.1MHz Switching Frequency with Three Modes  
of Operation  
The MAX16904 operates at a 2.1MHz frequency, allow-  
ing for small external components and reduced output  
ripple. It guarantees no AM band interference. SYNC  
input programmability enables three frequency modes for  
optimized performance: forced fixed-frequency operation,  
SKIP mode (ultra-low quiescent current of 25μA), and  
synchronization to an external clock. The MAX16904 can  
be ordered with spread-spectrum frequency modulation,  
designed to minimize EMI-radiated emissions due to the  
modulation frequency.

Forced Fixed-Frequency Operation  
External Frequency Synchronization  
● Optional Spread-Spectrum Frequency Modulation  
Power-Good Output  
● Enable-Pin Compatible from +3.3V Logic Level  
to +42V  
Thermal Shutdown Protection  
The MAX16904 is available in a thermally enhanced,  
3mm x 3mm, 10-pin TDFN package or a 16-pin TSSOP  
package. The MAX16904 operates over the -40°C to  
+125°C automotive temperature range.
