The SDC10 module is a low-noise DC/DC converter operating from a single +24VDC input. It is designed to supply sensitive systems.
To achieve low-noise operation, the SDC10 features a high-frequency DC/DC push-pull converter and a low-dropout voltage regulator. High-frequency operation leads to smaller transformer and filter while the 50% push-pull topology reduces the ripple at both input and output. The on-board PWM oscillator can be synchronized with an external source. A shut-down input is also provided to disable the power switches. Stable output voltage and further ripple attenuation are achieved with the LDO regulator. In addition, the circuitry includes a soft-start function and a current limitation. Since the SDC10 provides an isolated output, the module can easily supply a negative voltage. Two 6-pin connectors allow the module to be plugged into a carrier board.
