NCV7691LBGEVB
NCV7691 Load Board
Evaluation Board
User's Manual
Description
The NCV7691GEVB Current Controller with
Automotive LED Lamps in Sequencing Application
Evaluation Board has an edge connector feature which
allows for an external connection of LEDs. This board
connects to the edge connector to display LEDs in addition
to the LED array on the board.
Four boards with different LED footprints will fit many
standard LED components. Each board has a connector for
the controller board VBB and 3 strings of 4 LEDs in series.
If you are only using 3 LEDs in your string, a short across
the unpopulated footprint will complete the circuit.
Instructions for setting current levels and guiding the
circuit to the edge connector are include in the
NCV7691GEVB user manual.

EVAL BOARD USER’S MANUAL
Features
•
Provides a Platform to Display Design Target LEDs
•
Options for 4 Different LED Footprints
Figure 1. NCV7691 Optional External LED Load Boards
The Load boards are designed for standard LED
components, but alternative components may be populated
Figure 4. Load Board Interface with Controller Board
The connections in the load board provide a path between
VBB and each individual string as shown in Figure 2.
Figure 3 shows the load board interfaced to the controller
board. The jumpers labled for “OFF−BOARD” should be
moved to their proper position (right) for use. Figure 4
shows the Edge Connector points if an additional load board
is desired. It is also simple to connect to the edge connector
with clip leads for easy access to the driver points.
It is best to remove the LED array from the board when
using the external LED boards to avoid high current damage
to the LED array.
