Industrial DC/DC switch mode power supplies (SMPS) must achieve high efficiency at high switching frequencies and within tight heat dissipation constraints. They must also deliver fast transient response, wide input-voltage tolerance, and robust protection against overvoltage, overcurrent, and short-circuit events.
Vishay offers TrenchFET® MOSFETs and high voltage SiC MOSFETs for low switching loss at high frequency conversion and Schottky diodes for fast, low-Vf rectification at the output. Our IHLP® / IHLE® shielded inductors reduce magnetic loss and EMI and aluminum electrolytic and MLCC ceramic capacitors handle energy storage and output filtering. Low TCR thin film resistors provide voltage and current sensing, TVS diodes handle transient overvoltage, and optocouplers isolate the feedback loop.
For integrated point of load designs, Vishay's DC/DC regulator modules integrate the controller, power MOSFETs, and inductor into a single package with thermal coupling between the FET and inductor, eliminating PCB interconnect parasitics and reducing external component count.
