MAX38913A WLP

Evaluation Kit

Evaluates: MAX38913

319-100697; Rev 0; 3/21

General Description

The MAX38913A WLP evaluation kit (EV kit) evaluates the

MAX38913A in a wafer-level package (WLP). The

MAX38913A is a low-noise linear regulator. The EV kit

operates over an input range of 1.8V to 5.5V. The EV kit

provides an output voltage that is jumper selectable

between two separate levels. Each of the two regulated

output levels are configured to one of the 33 possible

voltages

through

external

select

resistors.

The

MAX38913A EV kit features a pass-through mode that can

completely bypass the linear regulator. The EV kit can

deliver up to 1A of current.

Quick Start

Required Equipment

• MAX38913A WLP EV Kit

• 1.8V to 5.5V, 3A DC power supply (IN)

• Electronic load capable of 1A

• Digital voltmeter (DVM)

Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify the board operation.

Caution: Do not turn on power supply until all

connections are completed.

1. Verify that jumper RSEL1 is opened (VSEL1 is set to

3.6V).

2. Verify that jumper RSEL2 is opened (VSEL2 is set to

1.8V).

3. Verify that jumpers EN2 and EN1 are shunted on pins

1 and 2 (OUT = VSEL2).

4. Connect the 5.5V power supply between the IN and

nearest GND terminal posts.

5. Connect the 1A electronic load between the OUT and

nearest GND terminal posts.

6. Connect the DVM between the OUT and nearest GND

terminal posts.

7. Turn on the power supply.

8. Verify that the voltage at the OUT terminal post is 1.8V

within the device and the RSEL resistors accuracy

specifications.

9. Enable the electronic load.

10. Verify that the voltage at the OUT terminal post is 1.8V

within the device and the RSEL resistors accuracy

specifications.

11. Move the shunt on Jumper EN2 to pins 2 and 3, Jumper

EN1 still shunt on pins 1 and 2, (OUT = VSEL1)

12. Verify that the voltage at the OUT terminal post is 3.6V

within the device and the RSEL resistors accuracy

specifications.
