EVALUATION KIT AVAILABLE  
MAX15026  
Low-Cost, Small, 4.5V to 28V Wide Operating  
Range, DC-DC Synchronous Buck Controller  
General Description  
Features  
o 4.5V to 28V or 5V 1ꢀ0 ꢁnpꢂt ꢃꢂpply ꢄange  
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.  
o ꢀ.6V to (ꢀ.85 x V ) Adjꢂstable Oꢂtpꢂt  
o Adjꢂstable 2ꢀꢀkHz to 2MHz ꢃwitching Freqꢂency  
o Ability to ꢃtart into a Prebiased Load  
o Lossless, Cycle-by-Cycle Valley Mode Cꢂrrent  
Limit with Adjꢂstable, Temperatꢂre-Compensated  
Threshold  
ꢁN  
o ꢃink-Mode Cꢂrrent-Limit Protection  
o Adaptive ꢁnternal Digital ꢃoft-ꢃtart  
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.

Sink-mode current limit prevents reverse inductor cur-  
rent from reaching dangerous levels when the device is  
sinking current from the output.  
The MAX15026 is available in a space-saving and ther-  
mally enhanced 3mm x 3mm, 14-pin TDFN-EP pack-  
age. The MAX15026 operates over the extended -40°C  
to +85°C and automotive -40°C to +125°C temperature  
ranges.  
+Denotes a lead(Pb)-free/RoHS-compliant package.  
*EP = Exposed pad. T = Tape and reel.  
/V denotes an automotive qualified part.  
MAX15026D recommended for new designs.  
The MAX15026C is designed to provide additional mar-  
gin for break-before-make times.  
Pin Configuration  
The MAX15026B/MAX15026C provide a soft-stop  
feature to ramp down the output voltage at turn-off. The  
soft-stop function is disabled in the MAX15026D.
