TEST CONFIGURATIONS
Input Reflected Ripple Current Test Step
Input reflected ripple current is measured through
a source inductor Lin(12uH) and a source capacitor
Cin(47uF, ESR<1.0© at 100KHz) at nominal input and
full load.

Output Ripple & Noise Measurement Test
To reduce ripple and noise, it is recommended to
use a 1uF ceramic disk capacitor and a 10uF ceramic
disk capacitor to at the output.

DESIGN & FEATURE CONFIGURATIONS
Over Voltage Protection
The module includes an internal output over voltage
protection circuit, which monitors the voltage on the
output terminals. If this voltage exceeds the over voltage
set point, the module will activate the control loop of
internal circuit to clamp the output voltage.
Over Current Protection
The module includes an internal over current protection
circuit, which will endure current limiting for an unlimited
duration during output over load condition. If the output
current exceeds the OCP set point, the module will shut
down automatically (hiccup).
Over Temperature Protection
The over temperature protection consists of circuitry
that provides protection from thermal damage. If the
temperature exceeds the over temperature threshold
the module will shut down.
The module will try to restart after shut down.
If the over load condition still exists, the module will
shut down again.
CTRL Module ON / OFF
The module will try to restart after shut down, If the
over temperature condition still exists during restart,
the module will shut down again. This restart trial will
continue until the temperature is within specification.
EMI Filter
Positive logic turns on the module during high logic and
off during low logic.
Ctrl module on/off can be controlled by an external
switch between the ctrl terminal and -Vin terminal.
The switch can be an open collector or open drain
Input filter components (C1,L) are used to help
meet conducted emissions .
These components should be mounted as close as
possible to the module; and all leads should be minimized
to decrease radiated noise.
For positive logic if the ctrl feature is not used,
please leave the ctrl pin floating.
