This design idea (DI) takes an unusual path to a power-handling DAC by merging an upside-down LM337 regulator with a simple (just one generic chip) PWM circuit to make a 20-V, 1-A current source. It’s ...

Demand for voltage-controlled current sources (VCCSs) and multipliers in a wide spectrum of electronics and communication devices always seems to exist. The multipliers employed in circuits like ...

For the circuit shown, a maximum current of 20 mA is feasible for a maximum load of 1100 Ohms. Using higher-voltage op amps and larger power transistors can increase these values if cost isn't a ...

Current-mode control LLC considerations Inductor-inductor-capacitor (LLC) serial resonant circuits, as shown in Figure 1, can achieve both zero voltage switching on the primary side and zero current ...
