This design idea reprises another “1A, 20V, PWM controlled current source.” Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 ...
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 the ...
Lively discussions have sprung up here in editor Aalyia Shaukat’s Design Ideas regarding the limitations and quirks of, and design tricks for, the current control topologies shown in Figure 1. Figure ...
It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...
