INTRODUCTION
The MIC24045 Evaluation Board requires only a single power supply with at least 5A
current capability. The MIC24045 has an internal V
DDA
LDO, so no external linear
regulator is required to power the internal biasing of the device.

GETTING STARTED
To power up the MIC24045 Evaluation Board, the following steps must be completed:
1. Connect a power supply to the V
IN
and G
ND
terminals. An ammeter may be
placed between the input supply and the V
IN
terminal of the evaluation board.
Ensure that the supply voltage is monitored at the V
IN
terminal (TP2 or J6). The
ammeter and/or power lead resistance can reduce the voltage supplied to the
input. Keep the power supply disabled; do not apply power until
Step 5.
2. Connect the load to the V
OUT
and G
ND
terminals.The load can be either passive
(resistive) or active (electronic load). An ammeter can be placed between the
load and the V
OUT
terminal. Ensure that the output voltage is monitored at the
V
OUT
terminal (TP3 or J7). Alternatively, for high-speed load transient testing at
low output voltages, the on-board load transient generator can be used (see
Section 2.3 “On-Board Load Transient Generator”
).
3. Make sure that a jumper is connected on J19, between V
BUS
and PWR, and
another jumper on J1, between V
IN
and V
INLDO
.
4. Connect the USB to Micro USB Cable (see
Figure 2-1
).
