Getting Started

Figure 2-1 highlights the user interface items associated with the EVM. The polarized VIN power terminal block (TB1) is used for connection to the host input supply and the polarized VOUT power terminal block (TB2) is used for connection to the load. These terminal blocks can accept up to 16-AWG wire.

The VIN monitor and VOUT monitor test points located near the power terminal blocks are intended to be used as voltage monitoring points where voltmeters can be connected to measure VIN and VOUT. The voltmeter references should be connected to the PGND test points located beneath the power terminal blocks. Do not use these VIN and VOUT monitoring test points as the input supply or output load connection points. The PCB traces connecting to these test points are not designed to support high currents.

The VIN scope (J1) and VOUT scope (J2) test points can be used to monitor VIN and VOUT waveforms with an oscilloscope. These test points are intended for use with un-hooded scope probes outfitted with a low-inductance ground lead (ground spring) mounted to the scope barrel. The two sockets of each test point are on 0.1-inch centers. The scope probe tip should be connected to the socket labeled VIN or VOUT, and the scope ground lead should be connected to the socket labeled PGND.

The test points located directly below the device are made available to test the features of the device. Any external connections made to these test points should be referenced to one of the PGND test points located along the bottom of the EVM. Refer to Section 3 for more information on the individual control test points.

The VOUT SELECT jumper (P1) is provided for selecting the desired output voltage. Before applying power to the EVM, ensure that the jumper is present and properly positioned for the intended output voltage.
