    A Voltage Regulator to Keep Pluggable Optics Plugging Away (opens the original)

    Excerpt · English

    Read excerpt

    Many power-supply ICs are designed to work with a wide range of applications. However, some applications require precisely controlled voltages at high currents, calling for a more tailor-made power-supply solution. Optical transceivers in data centers, for instance, require a unique power supply. Load transients must be regulated quickly to ensure that the supply voltage deviates only slightly from its nominal value. This is also the case for DRAM and other memory chips, which are evolving to us

    Power Sequencing, Simplified (opens the original)

    Excerpt · English

    Read excerpt

    From graphics processor units (GPUs) and central processing units (CPUs) to field-programmable gate arrays (FPGAs), digital signal processors (DSPs), and heterogeneous SoCs, every processor requires power sequencing. These digital loads often operate from multiple voltage rails, each of which may supply a different on-chip power domain. Power sequencing is the process of applying and removing power from these voltage rails in a specific order during system startup and shutdown. If the appropriat

    Evaluating Power Supplies with Different Compensation Settings (opens the original)

    Excerpt · English

    Read excerpt

    Power supplies are usually intended to generate a fixed, stable output voltage. The output must not oscillate, and it should remain constant with load transients and changes in the input voltage. To optimize the control loop of a switch-mode power supply, compensation pins are present in many power-supply ICs. These pins can be wired with appropriate compensation components, capacitances, and resistors to optimize the control loop to achieve the highest control bandwidth while ensuring loop stab
