说明
- 1% Error, 0-5 V Input, 0-500 mA output, low-side voltage to current (V-I) converter. This low-side voltage-to-current (V-I) converter delivers a well-regulated current to a floating load. The design uses a small-signal Op-Amp to control an NPN emitter-follower that sources current to the load. The current is accurately regulated by feeding back the voltage drop across a low-side current-sense resistor to the Op-Amp
