Quick Start
Recommended Equipment
• MAX17127 EV kit
• 5V to 26V power supply (VIN)
• 5V to 26V power supply (VIN)
Procedure
The EV kit is fully assembled and tested. Follow the
steps below to verify board operation. Caution: Do not
turn on the power supply until all connections are
completed.
1) On the EV kit, verify that the shunts are installed, as
steps below to verify board operation. Caution: Do not
turn on the power supply until all connections are
completed.
1) On the EV kit, verify that the shunts are installed, as
shown in Table 1.
2) Connect the positive terminal of the VIN power
supply to the VIN pad. Connect the ground terminal
of the VIN power supply to the PGND pad.
of the VIN power supply to the PGND pad.
3) Set the VIN power supply to 12V and enable its output.
4) Verify that the six strings of WLEDs are on.
4) Verify that the six strings of WLEDs are on.
Detailed Description of Hardware
The MAX17127 evaluation kit (EV kit) operates on a 5V
to 26V wide-input voltage range and provides adjust-
able 10mA to 30mA full-scale LED current. The EV kit
utilizes a step-up DC-DC converter to generate the
voltage required to drive up to six strings of 10 surface-
mount WLEDs.
