Quick Start

Recommended Equipment

• MAX17410 EV kit

• 7V to 24V, > 100W power supply, battery, or note-

book AC adapter

• 5V at 1A DC bias power supply

• Two loads capable of sinking 19A each

• Digital multimeters (DMMs)

• 100MHz dual-trace oscilloscope

Procedure

The MAX17410 EV kit is fully assembled and tested.

Follow the steps below to verify board operation:

1) Ensure that the circuit is connected correctly to the

supplies and dummy load prior to applying any

power.

2) Verify that all positions of switch SW2 are off. The

DAC code settings (D6–D0) are set by switch SW1.

Set SW1 (1, 14), SW1 (3, 12), SW1 (5, 10), SW1 (7, 8),

and SW1 (7, 8) to the on positions. The output voltage

is set for 0.9750V.

3) Turn on the battery power before turning on the 5V

bias power.

4) Observe the 0.9750V output voltage with the DMM

and/or oscilloscope. Look at the LX switching

nodes and MOSFET gate-drive signals while vary-

ing the load current.

Detailed Description of Hardware

This 38A multiphase buck-regulator design is opti-

mized for a 300kHz switching frequency (per phase)

and output-voltage settings around 1V. At VOUT = 1V

and VIN = 10V, the inductor ripple is approximately

45% (LIR = 0.45). The MAX17410 controller interleaves

all the active phases, resulting in out-of-phase opera-

tion that minimizes the input and output filtering

requirements. The multiphase controller shares the cur-

rent between two phases that operate 180° out-of-

phase supplying up to 19A per phase. Table 1 lists the

MAX17410 operating mode truth table function.
