2 Test Point Descriptions

Wire-loop test points and scope probe sockets are included for digital voltmeters (DVM) or oscilloscope probes to aid in the evaluation of the device. A description of each test point follows:

Table 2-1 Test Point Descriptions
Name(1) Description
VIN S+ Input voltage monitor. Connect the positive lead of a DVM to this point for measuring efficiency.
VIN S-Input voltage monitor. Connect the negative lead of a DVM to this point for measuring efficiency.
VOUT1 S+Output 1 voltage monitor. Connect the positive lead of a DVM to this point for measuring efficiency, line regulation and load regulation.
VOUT1 S-Output 1 voltage monitor. Connect the negative lead of a DVM to this point for measuring efficiency, line regulation and load regulation.
VOUT2 S+Output 2 voltage monitor. Connect the positive lead of a DVM to this point for measuring efficiency, line regulation and load regulation.
VOUT2 S-Output 2 voltage monitor. Connect the negative lead of a DVM to this point for measuring efficiency, line regulation and load regulation.
VOUT3 S+Output 3 voltage monitor. Connect the positive lead of a DVM to this point for measuring efficiency, line regulation and load regulation.
VOUT3 S-Output 3 voltage monitor. Connect the negative lead of a DVM to this point for measuring efficiency, line regulation and load regulation.
AGNDAnalog ground test point.
PGNDPower ground test point.
VOUT SCOPE (J2, J9, J14)Output voltage scope monitor. Connect an oscilloscope probe to this set of points to measure output ripple voltage and transient response.
ENABLE (J5, J8, J15)For ease of use, J13 can be set in the ON position to enable the device or in the OFF position to disable the device.
PGOOD1Monitors the power good signal of Channel 1 output. This is an open drain signal.
PGOOD2Monitors the power good signal of Channel 2 output. This is an open drain signal.
PGOOD3Monitors the power good signal of Channel 3 output. This is an open drain signal.
SYNC1&2Synchronization input test point of U1. When synchronizing to an external clock connect to this test point.
SYNC 3Synchronization input test point of U2. When synchronizing to an external clock connect to this test point.
