40V, High-Performance, Synchronous

Buck Controller

General Description

Features

S Input Voltage Ranges from 4.5V to 40V or 5V

Q10%

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.

S Adjustable Outputs from 0.85 x V Down to 0.6V

S Adjustable Switching Frequency (100kHz to 1MHz)

with Q10% (1MHz) Accuracy

S Adaptive Internal Digital Soft-Start

S Up to 25A Output Capability

S Cycle-by-Cycle Valley-Mode Current Limit with

Adjustable, Temperature-Compensated Threshold

(30mV to 300mV)

S Monotonic Startup into Prebiased Output

S Q1% Accurate Voltage Reference

S 3A-Peak Gate Drivers

The MAX15046 offers the ability to adjust the switching

frequency from 100kHz to 1MHz with an external resis-

tor. The MAX15046’s adaptive synchronous rectifica-

tion 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 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 for power sequencing.

S Hiccup-Mode Short-Circuit Protection (Patent-

Pending Architecture)

S Overtemperature Shutdown

S Power-Good (PGOOD) Output and Enable Input

(EN) with Q5% Accurate Threshold

S Thermally Enhanced 16-Pin QSOP Package

Applications

Industrial Power Supplies (PLC, Industrial

Computers, Fieldbus Components, Fieldbus

Couplers)

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.
