5.1 Test Equipment
Voltage Source:
• VIN: The input voltage source VIN should be a 0-V to 6-V variable DC source capable of supplying 8
A
DC
. Connect VIN to J1 as shown in Figure 3 .
• V5IN: The V5IN voltage source should be a 5-V DC source capable of supplying 1 A
DC
. Connect V5IN
to J3 as shown in Figure 3 .
Multimeters:
• V1: VIN at TP1 (VIN) and TP2 (PGND), 0-V to 6-V voltmeter
• V2: V5IN at TP3 (V5IN) and TP4 (PGND)
• V3: VOUT at TP5 (VOUT) and TP6 (PGND)
• A1: VIN input current, 0 A
DC
to 8 A
DC
Ammeter
Output Load: The output load should be an electronic constant resistance mode load capable of 0 A
DC
to
10 A

Fan: Some of the components in this EVM may approach temperatures of 55ºC during operation. A small
fan capable of 200 LFM to 400 LFM is recommended to reduce component temperatures while the EVM is
operating. The EVM should not be probed while the fan is not running.
Recommended Wire Gauge:
• VIN to J1 (1.2-V input): The recommended wire size is 1x AWG #14 per input connection, with the
total length of wire less than 4 feet (2 feet input, 2 feet return).
• J2 to LOAD: The minimum recommended wire size is 1x AWG #14, with the total length of wire less
than 4 feet (2-feet output, 2-feet return)
• V5IN to J3 (5-V input): The recommended wire size is 1x AWG #16 per input connection, with the
total length of wire less than 4 feet (2-feet input, 2-feet return).
