Reference Designs
Small Negative Bias Supply for Low Noise Applications Reference Design
Texas Instruments
This circuit reference design is realized in Cuk Topology. The output voltage is -12V / -15V. The output current of 200mA is possible over an input voltage range of 10V to 60V (even with a low input voltage of 6V 140mA output current is possible). The perfect switching behavior of the circuit results in lowest radiated emissions.
Features
- Cost effective (LM5001: TLV271)Suitable for audioDespite Cuk topology: excellent dynamic behaviorLowest ripple at input and outputTransient response on a 50% load step is only 1%The circuit reference design is built and tested
Applications
- Battery cell formation & test equipment
