Buck Boost Regulator Evaluation; Power Supervisory Evaluation - Analog Devices ADP5360 User Manual

UG-1571
Measure Load Regulation
After the VOUT1 board terminal voltage reaches 1.2 V,
increase the load current at VOUT1 before checking the voltage
between VOUT1 and GND with the voltage meter.
Measure Regulator Efficiency
The regulator efficiency is measured by dividing input power
by output power.
Change Buck Soft Start Time
Set the soft start time in the BUCK_SS bits in the Buck Setting
box (see Figure 21).The default soft start time is 1 ms and users
must select a different soft start time. The soft start time options
are 1 ms (not recommended), 8 ms, 64 ms, and 512 ms.

BUCK BOOST REGULATOR EVALUATION

Set the EN_BUCKBST bit (see Figure 22) high to enable the
buck boost regulator.
The default buck boost regulator output voltage is 5 V.
Program the VOUT_BUCKBST bits (see Figure 22) to set the
output voltage.

Measure Load Regulation
After the VOUT2 board terminal voltage reaches 5 V, increase
the load current at VOUT2, then check the voltage between the
on-board VOUT2 and GND.
Measure Regulator Efficiency
The efficiency is measured by dividing the input power by the
output power.
Change Buck Boost Soft Start Time
Set the soft start time for the BUCKBST_SS bits in the Buck
Boost Setting box (see Figure 22). The default soft start time is
1 ms and users must select a different soft start time. The soft
start time options are 1 ms (not recommended), 8 ms, 64 ms,
and 512 ms.

POWER SUPERVISORY EVALUATION

In the Supervisory Setting box (see Figure 23), set the EN_WD
bit high to enable the watchdog function. Program the watchdog
timeout through the WD_TIME bits (see Figure 23). Click the
RESET WD button, located above the WD_TIME box, to
toggle the ADP5360
