2.0 Test Configuration
3.0 Procedure
3.1 Configure equipment as shown in Figure 1. Set current limits for DC
supplies as listed in section 1.0.
3.2 Turn on power supplies in the following order: 12 V, 5 V, 3.3 V. Verify that
input currents do not exceed current limits.
3.3 Apply 17 A constant current electronic load or resistive load as described in
section 1.0. Verify that output maintains 1.5 V ±10% while under load.
3.4 Ground oscilloscope to any GND and probe switch nodes on 3.3 V and 5 V
sides. Verify that switching frequency is 300 kHz ±10% and that there is no
excessive jitter.
3.5 Remove load. Briefly short VOUT to GND. Verify that board does not
destabilize while shorted (no hissing, squealing, or excessive heat dissipation).
3.6 Turn off power supplies in the following order: 3.3 V, 5 V, 12 V.
