LMP8646 Precision Current Limiter 1 1 Features 1• Provides Circuit Protection and Current Limiting • Single Supply Operation PSRR Power Supply Rejection Ratio VCM = 2.1 V, 2.7 V < V+ < 12 V 85 dB CMRR Common-Mode Rejection Ratio 2.1 V < VCM < 76 V 95 dB -2 V (V out / I out) then power supply is in CV mode. · If R load < (V out / I out) then power Yes, everything must be within the limits of a CV or CC supply. In the example in my previous post with the 100 A PSU set to 12 V and a current limit of 1 A, you will have noticed that it operates EITHER in CV mode OR in CC mode, depending on the load. With too low a load, it cannot work in CC mode. With too high a load, it cannot work in CV mode. Those circuits are combined to create an analog variable bench power supply which generate .0V-28V and .0A-2A with precision current limiter. The regulation and noise floor performance is pretty good in comparison with similer DC-DC converter based power supplies. Vay Nhanh Fast Money.
