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 describes each test point.
| Test Point(1) | Description |
|---|---|
| VIN S+ | Input voltage monitor. Connect the positive lead of a DVM to this point for measuring efficiency. |
| VIN S- | Input ground monitor. Connect the negative lead of a DVM to this point for measuring efficiency. |
| VOUT S+ | Output voltage monitor. Connect the positive lead of a DVM to this point for measuring efficiency, line regulation, and load regulation. |
| VOUT S- | Output ground monitor. Connect the negative lead of a DVM to this point for measuring 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 | Power good 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. |
