Low-Cost, Small, 4.5V to 28V Wide Operating  
Range, DC-DC Synchronous Buck Controller  
MAX15026  
General Description  
Features  
The MAX15026 synchronous step-down controller oper-  
ates from a 4.5V to 28V input voltage range and gener-  
ates an adjustable output voltage from 85% of the input  
voltage down to 0.6V while supporting loads up to 25A.  
The device allows monotonic startup into a prebiased  
bus without discharging the output and features adap-  
tive internal digital soft-start.

Thrgshoꢂd  
The MAX15026 offers the ability to adjust the switching  
frequency from 200kHz to 2MHz with an external resis-  
tor. The MAX15026’s adaptive synchronous rectification  
eliminates the need for an external freewheeling  
Schottky diode. The device also utilizes the external  
low-side MOSFET’s on-resistance as a current-sense  
element, eliminating the need for a current-sense resis-  
tor. This protects the DC-DC components from damage  
during output overloaded conditions or output short-  
circuit faults without requiring a current-sense resistor.  
Hiccup-mode current limit reduces power dissipation  
during short-circuit conditions. The MAX15026 includes  
a power-good output and an enable input with precise  
turn-on/turn-off threshold, which can be used for input  
supply monitoring and for power sequencing.

Additional protection features include sink-mode cur-  
rent limit and thermal shutdown.  
Ordering Information  
Sink-mode current limit prevents reverse inductor cur-  
rent from reaching dangerous levels when the device is  
sinking current from the output.
