Beschreibung
- AMD Athlon Processor Power Supply circuit. The design is quite straightforward: there are essentially two identical synchronous buck regulators connected in parallel. The controller drives them 180 out of phase. The LTC1929 has large gate drivers (approximately 1.5W) so it can drive large MOSFETs efficiently
