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 inputvoltage down to 0.6V while supporting loads up to 25A.The device allows monotonic startup into a prebiasedbus without discharging the output and features adaptiveinternal digital soft-start.The MAX15026 offers the ability to adjust the switchingfrequency from 200kHz to 2MHz with an external resis-tor. The MAX15026’s adaptive synchronous rectificationeliminates the need for an external freewheeling Schottkydiode. The device also utilizes the external low-sideMOSFET’s on-resistance as a current-sense element,eliminating the need for a current-sense resistor. This pro-tects the DC-DC components from damage during outputoverloaded conditions or output shortcircuit faults withoutrequiring a current-sense resistor. Hiccup-mode currentlimit reduces power dissipation during short-circuit condi-tions. The MAX15026 includes a power-good output andan enable input with precise turn-on/turn-off threshold,which can be used for input supply monitoring and forpower sequencing.Additional protection features include sink-mode currentlimit and thermal shutdown.Sink-mode current limit prevents reverse inductor currentfrom reaching dangerous levels when the device is sink-ing current from the output.The MAX15026 is available in a space-saving and thermal-ly enhanced 3mm x 3mm, 14-pin TDFN-EP package. TheMAX15026 operates over the extended -40°C to +85°Cand automotive -40°C to +125°C temperature ranges.The MAX15026C is designed to provide additional marginfor break-before-make times.The MAX15026B/MAX15026C provide a soft-stop featureto ramp down the output voltage at turn-off.
