5 Test Setup
5.1 Test Equipment
Voltage Source VIN: The input voltage source VIN must be a 0-V to 14-V variable dc source capable of
supplying 10 Adc. Connect VIN to J304 as shown in Figure 7.
Multimeters:
V1: Vin at TP303 (VIN) and TP304 (GND)
V2: Vout at each output test point. For example: CPU at J101
A1: Vin input current
Output Load: The output load must be an electronic constant resistance mode load capable of 0 Adc to
10 Adc.
Oscilloscope: A digital or analog oscilloscope can be used to measure the output ripple. The oscilloscope
must be set for 1-MΩ impedance, 20-MHz bandwidth, ac coupling, 2-µs/division horizontal resolution,
50-mV/division vertical resolution. Test points on each output can be used to measure the output ripple
voltage. Do not use a leaded ground connection as this may induce additional noise due to the large
ground loop.
Recommended Wire Gauge:
1. VIN to J304 (12-V input):
The recommended wire size is AWG 16 per input connection, with the total length of wire less than 4
feet (2-foot input, 2-foot return).
2. Each outputs to LOAD:
The minimum recommended wire size is AWG 16, with the total length of wire less than 4 feet (2-foot
output, 2-foot return)
5.2 Recommended Test Setup
Figure 7. TPS59610EVM-634 Recommended Test Setup
Figure 7 is the recommended test setup to evaluate the TPS59610EVM-634. Working at an ESD
workstation, ensure that wrist straps, bootstraps, or mats are connected referencing the user to earth
ground before handling the EVM.
