General Description

The MAX15046 synchronous step-down controller operates from a 4.5V to 40V input voltage range and generates an adjustable output voltage from 85% of the input voltage down to 0.6V, supporting loads up to 25A.

The device allows monotonic startup into a prebiased bus without discharging the output and

Key Features

  • adaptive internal digital soft-start. The MAX15046 offers the ability to adjust the switching frequency from 100kHz to 1MHz with an external resistor. The MAX15046’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 resistor. This protects the DC-DC components from damage during output overloaded conditions or.
