PERFORMANCE EVALUATION
The following sections discuss tests and the resulting oscil-
loscope waveforms. Oscilloscope waveforms and typical
performance characteristics are provided in the ADP1612/
ADP1613 data sheet.
Line Regulation
The line regulation is observed and measured by monitoring
the output voltage (VOUT) while varying the input voltage (VIN).
Load Regulation
The load regulation is observed and measured by monitoring
the output voltage (VOUT) while sweeping the applied load
between VOUT and GND. To minimize voltage drop, use short
low resistance wires, especially for heavy loads.
Efficiency
The efficiency, η, is measured by comparing the input power to
the output power

Line Transient
The line transient performance is evaluated by generating a
high speed voltage transient on the input (VIN) and observing
the behavior of the evaluation module at the inductor (SW) and
the output (VOUT.)
Load Transient
The load transient performance is evaluated by generating a fast
current transient on the output (VOUT) and observing the
behavior of the evaluation module at the inductor (SW) and the
output (VOUT.)
Oscillator Frequency
The oscillator frequency can be measured by connecting an
oscilloscope to the SW pin.
Inductor Current
The inductor current is made accessible by removing one side
of the inductor from its pad and connecting a current loop in
series. Place an oscilloscope current probe on the loop to view
the current waveform.
