Application Note 1558
DIP-Switch Descriptions
? S1: Set the control signals
? TP6: Monitor the FB pin.
? TP7: Monitor the DPRSLPVR pin.
- S1.1: Set
- S1.2: Set
? U2: Set the
the DPRSLPVR signal
the PSI# signal
VID
? TP8: Monitor the VR_TT# pin.
? TP9: Monitor the PSI# pin.
? TP10: Monitor the ISEN3/FB2 pin.
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 ISL62882 is configured for 3- or 2-phase
application. Tie ISEN2 to 5V when the ISL62882 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 ISL62882 is configured for 3-, 2-phase
application. Leave ISEN1 floating when the
ISL62882 is configured for 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.
Test-point Descriptions
? J7: Scope-probe socket for measuring PHASE1
? J8: Scope-probe socket for measuring PHASE2
? J9: Scope-probe socket for measuring PHASE3
? J10: Scope-probe socket for measuring V O
? J15: Scope-probe socket for measuring the current
of the on-board transient-load emulator
? TP1: Monitor the on-board 1.2V power supply
? TP2: +12V power supply return input.
? TP3: +12V power supply positive input.
? TP4: Monitor the COMP pin
? TP5: Monitor the VW pin.
2
? TP11: Monitor the ISEN2 pin.
? TP12: Input side of the compensator.
? TP13: Monitor the PGOOD pin.
? TP14: Monitor the VSEN pin.
? TP15: Monitor the ISEN1pin.
? TP16: Monitor the CLK_EN# pin.
? TP17: Monitor the VR_ON pin
? TP18: Monitor the RTN pin.
? TP19: Monitor the positive side of C82.
? TP20: Monitor the negative side of C82.
? TP21: Monitor the VID6 pin.
? TP22: Monitor the VID5 pin.
? TP23: Monitor the VID4 pin.
? TP24: Monitor the VID3 pin.
? TP25: Monitor the VID2 pin.
? TP26: Monitor the VID1 pin.
? TP27: Monitor the VID0 pin.
? TP28: Monitor the IMON pin.
? TP29: +5V power supply positive input.
? TP30: +5V power supply return input.
? TP31: V IN positive voltage sense
? TP32: V IN return voltage sense
? TP33: Monitor MOSFET Q3 gate signal
? TP34: Monitor MOSFET Q9 gate signal.
? TP35: Monitor the VCCSENSE pin of the CPU
socket U4.
? TP36: Monitor the VSSSENSE pin of the CPU socket
U4.
? TP37: +3.3V power supply positive input.
? TP38: Monitor the VTT1 rail of the CPU socket U4.
? TP39: Monitor the VTT2 rail of the CPU socket U4.
