Output Ripple & Noise Measurement Test Measured with a 1.0uF MLCC capacitor and a 10uF tantalum capacitor . The Scope measurement bandwidth is 0-20MHz. Copper Strip Lin Current +Vin +Vout +Vout Probe Cin DC/DC Converter Load Single DC/DC Converter 1uF + 10uF Scope Resistive Load -Vin -Vout -Vout 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. + 10uF +Vin +Vout 10uF 1uF DC Power Source Cin Single DC/DC Converter Cout Load - -Vin -Vout 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. +Vin +Vout CTRL DC DC Converter Load -Vin -Vout 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.
