Introduction

AI Translation

The MAX15046 synchronous step-down controller oper­ ates from a 4.5V to 40V input voltage range and gener­ ates 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 features adaptive internal digital soft-start. The MAX15046 offers the ability to adjust the switching fre­ quency 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 con­ ditions or output short-circuit faults without requiring a current-sense resistor. Hiccup-mode current limit reduc­ es power dissipation during short-circuit conditions. The MAX15046 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 power sequencing. Additional protection features include sink-mode current limit and thermal shutdown. Sink-mode current limit pre­ vents reverse inductor current from reaching dangerous levels when the device is sinking current from the output. The MAX15046A/MAX15046B feature soft-stop opera­ tion. Soft-stop operation is disabled in the MAX15046C. The MAX15046 is available in a 16-pin QSOP or 16-pin QSOP-EP package and operates over the -40°C to +125°C temperature range.
