NCP5810DGEVB/D NCP5810D: Dual 1 W Output AMOLED Driver Supply Evaluation Board Prepared by: Hubert Grandry NCP5810DGEVB/D INPUT POWER Symbol Descriptions J1 1 This is the positive connection for power supply. The leads (positive + ground) to the input supply should be twisted and kept as short as possible. J1 2 This is the return connection for the power supply (Ground signal) J4, J5 Ground clip OUTPUT POWER Symbol Descriptions J3 1 This is the positive output connection (VOUTP) of the boost converter. J3 2 Ground to connect the load. J3 3 This is the negative output connection (VOUTN) of the inverter. OUTPUT SETUP Symbol Descriptions R6 This adjustable resistor setup the negative output voltage from 2.0 to 15 V. SWITCHES SETUP Symbol Switch Descriptions J2 To enable the converter connect a shorting jumper between J21 and J22 J6 SHORT True SD: Short the True Shutdown function: When a jumper is connected, the internal PMOS used disconnect the load from the battery is bypassed. J8 A solder dot can be place to short R6 in order to fix VOUTN by R4 and R5 only. TEST POINT Symbol Switch Descriptions TP1 Test point is directly connected to the PVIN pin to sense the battery voltage. TP2 This test point is connected to the SWP pin signal. TP3 This test point is connected to the positive output voltage: VOUTP TP4 This test point is directly connected to the AVIN pin to sense battery voltage. TP5 This test point is connected to the SWN pin signal. TP6 This test point is connected to the negative output voltage: VOUTN TP7 This test point is connected to the Vref pin signal. TP8 This test point is connected to the FBN pin signal. TP9 This test point is connected to the VS pin signal.
