Input Reflected Ripple Current Test Step

Input reflected ripple current is measured through

a source inductor Lin(12uH) and a source capacitor

full load.

Output Ripple & Noise Measurement Test

Measured with a 1.0uF MLCC capacitor and a 10uF

tantalum capacitor .

The Scope measurement bandwidth is 0-20MHz.

Output Ripple & Noise Reduction

To reduce ripple and noise, it is recommended to use a 1uF ceramic disk capacitor and a 10uF electrolytic

capacitor to at the output.

CTRL Module ON / OFF

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

For positive logic if the ctrl feature is not used, please leave the ctrl pin floating.

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).

The module will try to restart after shut down. If the over load condition still exists, the module will

shut down again.
