Introduction
The Texas Instruments LP8860-Q1EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the LP8860-Q1 device. The LP8860-Q1EVM uses the LP8860-Q1 to drive up to 4
LED strings for LCD backlighting with high efficiency. Information about output voltage and current ratings
of the LP8860-Q1 can also be found in the
In order to facilitate ease of testing and evaluation of this circuit, the EVM contains a TI MSP430
microprocessor to provide easy communication via USB. Power supply connection for the VIN, VDD, and
test points for each signal can be found on the evaluation board. Windows

C/SPI™ registers of the device. A separate LED board can be used as a load; it is also possible to
connect LCD panel to the output connectors.
For evaluation purposes, the EVM has been tested over a 3-V to 48-V input range. This voltage range is
within the recommended operating range for input voltage of the LP8860-Q1. Users are cautioned to
evaluate their specific operating conditions and choose components with the appropriate voltage ratings
before designing this support circuitry into a final product.
