  1. Various switching regulator circuits exist to provide positive- to-negative conversion. Unfortunately, most controllers cannot sense the negative output directly; they require a positive feedback signal derived from the negative output. This ...

  2. The circuits in Figures 1 and 2 shows a PWM (pulse-width-modulated) ramp generator that you can use in low-cost switch-mode dc/dc power supplies. Its supply voltage can range from 5 to 35 V dc, and you can set the output-ramp amplitude of 0.3 to 1 ...

  1. With linear regulators, you measure dropout voltage, V IN V OUT , at the minimum input voltage for which the IC sustains regulation. Low dropout means longer battery life, because the load circuit continues to operate while the battery discharges ...

  2. The circuit in Figure 1 allows standard TTL logic levels to safely drive a high-power dc load. The circuit provides for both signal and ground isolation as well as a solid-state circuit breaker. Figure 1. An overcurrent condition in this isolated ...

  6. In a three-phase ac system, a power source with three wires delivers ac potentials of equal frequency and amplitudes with respect to a zero-potential wire, each shifted in phase by 120 from one wire to the next. Two possibilities exist for ...

  7. Most battery chargers comprise nothing more than a series-pass regulator with current limit. In solar-powered systems, you can’t count on sufficient headroom to keep a series regulator alive, so a shunt method is preferred. A simple shunt ...

  8. You may lack experience and hardware when designing battery-operated products. The battery life of a product can depend more on the ESR (equivalent series resistance) than the terminal voltage. This situation is especially true when you use ...
