J9 – Input— This header is the power input (VBAT) terminal and also probing header for the boost
converter. The terminal provides a power connection to allow the user to attach the EVM to a power
supply and also monitor VBAT connected to J5.
J10 – Header — This header is a probing point of VIN (boost input power after power filters).
J11 – Header— This header is a probing point of VINP (boost input power after power line FET).
J12 – Headers— These headers are probing points of boost output (VBOOST).
J13 – GND— This header is the power input (GND) terminal and also probing header for the boost
converter. The terminal provides power ground connection to allow the user to attach the EVM to a
power supply and also monitor VBAT connected to J8.
J14 – Jumper— This connector is for selection of the source of VDDIO between VDD and internal LDO
out (V ) of LP8863-Q1.
LDO
J15 – Input— This header is the power input (VDDIO) terminal and also probing header for VDDIO. The
terminal provides a power connection to allow the user to attach the EVM to a power supply and
also monitor VDDIO selected by J14.
J16 – Headers— These headers are probing/noise injecting points for stability measurement of boost.
J17 – Connector— This connector is to connect VDD to the internal charge pump output (when charge
pump is not used).
J18 – Header— This header is a probing point of GD.
J19 – Jumper— This connector is for selection of the source of VDDIO between 1.8-V and 3.3-V output
from on-board LDOs.
J20 – Connector— This connector is to connect 5-V output from on-board LDO to VDD input.
J21 to J26 – Headers— These headers are to measure LED string current of LED0 to LED5.
J27 – GND— These headers are probing points of GND.
J28 – Header— This header is a probing point of INT.
J31 – Connector— This connector is to connect 5-V output from on-board LDO to VDD input.
J32 – Headers— These headers are probing points of SDO_PWM, SDI_SDA, SCLK_SCL, and
SS_ADDRSEL.
J33 – Connector— This connector is to connect LED load board to EVM.
J34 – GND— These headers are probing points of GND.
