MAX15041 Evaluation Kit

Evaluates: MAX15041

General Description

The MAX15041 evaluation kit (EV kit) is a fully assembled

and tested circuit board that evaluates the MAX15041

synchronous buck converter IC with integrated high-side

and low-side switches. The EV kit output is configured

to 3.3V and delivers up to 3A output current. The EV kit

circuit operates at the MAX15041 internally set 350kHz

switching frequency and features PCB pads to monitor

the IC power-good output signal (PGOOD) and to enable

the circuit.

The MAX15041 EV kit requires a 4.5V to 28V power

supply that provides up to 3A for normal operation.

MAX15041 Evaluation Kit Enable Control (JU1) Jumper JU1 configures the MAX15041 EV kit output for turn-on/turn-off control. Install a shunt across pins 1-2 to enable VOUT or across pins 2-3 to disable VOUT. VOUT can also be enabled by applying an external signal greater than 1.95V (typ) at the EN and SGND PCB pads. See Table 1 for proper JU1 configuration. Table 1.
