Introduction
The Texas Instruments TPS61177AEVM evaluation module (EVM) helps designers evaluate the operation
and performance of the TPS61177A High-Efficiency LED Backlight Driver. The device offers configurability
and can be set up to switch at 450 kHz, 600 kHz, 800 kHz, and 1.2 MHz.
The EVM contains one LED driver (see
Table 1
).

Set-Up
This section describes the jumpers and connectors on the EVM, as well as how to properly connect, set
up, and use the TPS61177AEVM.

Input/Output Connector Description
J1 - Input
: This header is the power input(VIN) terminal for the boost converter. The terminal provides a
power (VBAT) connection to allow the user to attach the EVM to a power supply.
J2 - Input
: This header is the power input (GND) terminal for the boost converter. The terminal provides a
power ground(PGND) connection to allow the user to attach the EVM to a power supply.
J3 - Input
: T his header is the power input terminal for the boost converter. The terminal provides a power
and power ground connection to allow the user to attach the EVM to a power supply using a 2-pin IDC
socket and also monitor VIN connected to J1.
J4 - Connector
: This connector is for interfacing LED load board via ribbon cable or flying wires.
J5 - GND
: This header connects to AGND to provide grounds for signal probing.
J6 - GND
: This header connects to AGND to provide grounds for signal probing.
J7 - Input
: This header connects to AGND to provide grounds for signal probing.
J8 - Connector
: This connector is for interfacing with USB2ANY interface board for I2C communication
and control inputs such as PWM and EN signal.
