  2. Introduction High voltage buck DC/DC controllers such as the LTC3890 (dual output) and LTC3891 (single output) are popular in automotive applications due to their extremely wide 4 V to 60 V input voltage range, eliminating the need for a snubber ...

  5. Designers often use chargers with flyback topologies to quickly charge energy-storage capacitors (references 1 and 2 ). In a flyback topology, the energy transfer takes place only when the charger’s power MOSFET is off, which effectively ...
