SMPS400 | Switch Mode Power Supply Series






The SMPS400 is a high efficiency Safety Class 2 switch mode power supply specifically designed for use with our range of UcD®amplifier modules. Key features are high efficiency over the entire load range, extremely small form factor, low weight and very low radiated and conducted EMI. The SMPS400 also features an advanced over current protection which in case of temporary overload simply reduces the output voltage, only when the overload condition remains for a longer time the supply will enter hiccup mode until the overload condition disappears. This feature combined with large electrolytic buffer capacitors leads to the capability of delivering high dynamic headroom power to the connected amplifier. The SMPS400 also includes an auxiliary isolated supply and a control circuit directly interfacing with our range of (OEM and standard) UcD®amplifier modules. The supply is triggered for normal operation or latched off in case of a critical fault via in built-in actuators. The SMPS400 is optimized from the first phase of design to final implementation to realize the low EMI signature required of the most demanding audio applications.
