Figure 1 LM337 mates with a generic hex inverter to make an inexpensive 1-A PWM current source.(* = 1% metal film) Iout = 1.07(DF – 0.07), Iout > 0. ACMOS inverters U1b through U1e accept a 10 kHz PWM ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

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 ...

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 ...
