EVM Connectors and Test Points

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. Table 2-1(1) describes each test point.

Table 2-1 Test Point Descriptions
TEST POINT DESCRIPTION
VIN S+ Input voltage monitor. Connect the positive lead of a DVM to this point to measure efficiency.
VIN S– Input ground monitor. Connect the negative lead of a DVM to this point to measure efficiency.
VOUT S+ Output voltage monitor. Connect the positive lead of a DVM to this point to measure efficiency, line regulation, and load regulation.
VOUT S– Output ground monitor. Connect the negative lead of a DVM to this point to measure efficiency, line regulation, and load regulation.
PGND Power ground test points
VIN Scope (J2) Input voltage scope monitor. Connect an oscilloscope probe to this set of points to measure input ripple voltage.
VOUT Scope (J3) Output voltage scope monitor. Connect an oscilloscope probe to this set of points to measure output voltage ripple and transient response.
EN Enable test point. Monitors the enable signal of the device. Use the ENABLE Control header (J5) to disable the device.
ENABLE Control (J5) Enable select jumper. Enable or disable the device using a jumper.
PGOOD Power-good test point. Monitors the power-good signal of the device. This is an open-drain signal. A 49.9-kΩ resistor is connected to this pin and the PG_PU pin on the EVM.
PG_PU PGOOD pullup test point. Apply a voltage to this pin to use as a pullup voltage for the PGOOD signal. A 49.9-kΩ resistor is connected to this pin and the PGOOD pin on the EVM.
