3.1.1 Start-Up Procedure

  1. The converter TPS923612 is enabled when the ADIM pin is pull up to VIN pin (short J6 pin1 and pin2 on EVM)
  2. J6 pin2 is the terminal for external enable and PWM dimming signal, PWM frequency range is 10KHz to 200KHz.
  3. A power supply capable of supplying 3A must be connected to PVIN (TP1) and GND (TP2), wires must be twisted and kept as short as possible to minimize voltage drop, inductance, and EMI transmission.
  4. Test point TP4 provides a place to monitor the PVIN input voltages. Test point TP6 is used to monitor the output voltage.
  5. J5 is used to select onboard or external LED load.
  6. Open or short J1S, J2S and J4S can change the White LED numbers from 1 to 9, make sure the VOUT drop on LED load is 5V or higher for proper operating.
