DIP-Switch Descriptions
? S1: Set the control signals
- S1.1: Set the DPRSLPVR signal
- S1.2: Set the PSI# signal
? U2: Set the VID
Jumper Descriptions
? J1: Set the ISEN2 pin configuration. ISEN2 can be
connected to the power stage, tied to +5V, GND or left
floating. Connect ISEN2 to the power stage when the
ISL62883 is configured for 3-phase or 2-phase
application. Tie ISEN2 to 5V when the ISL62883 is
configured for 1-phase application.
? J2: Set the ISEN1 pin configuration. ISEN1 can be
connected to the power stage, tied to +5V, GND or left
floating. Connect ISEN1 to the power stage when the
ISL62883 is configured for 3-phase, 2-phase application.
Leave ISEN1 floating when the ISL62883 is configured for
1-phase application
? J3: If installed, the ISEN3/FB2 pin will be connected to the
power stage. If uninstalled, the ISEN3/FB2 pin will be
disconnected from the power stage. Install J3 when the
ISL62883 is configured for 3-phase application. Uninstall
J3 when the ISL62883 is configured for 2-phase or
1-phase application.
? J4: Set the PWM3 pin configuration. PWM3 can be
connected to the ISL6208 driver, tied to +5V, GND or left
floating. Connect PWM3 to the ISL6208 driver when the
ISL62883 is configured for 3-phase application. Tie PWM3
to 5V when the ISL62883 is configured for 2-phase or
1-phase application.
? J16: If installed, the +5V rail supplies the +3.3V rail to the
auxiliary circuit on the board. DO NOT APPLY +3.3V TO
TP37/TP30 WHILE J16 IS INSTALLED! IT’LL SHORT
THE +5V AND THE +3.3V POWER SUPPLIES . When
measuring board efficiency, uninstall J16 and apply +3.3V
to TP/37/TP30.
