Abstract
Some implementations are directed to a A DC-to-DC converter that includes a power transformer having a primary side and a secondary side and a plurality of power transistors coupled to the primary side of the transformer. The converter also includes a secondary bias supply coupled to the secondary side of the transformer and a secondary side controller coupled to the secondary side of the transformer and configured to generate a feedback control signal based on a voltage level associated with the secondary side of the transformer. The secondary side controller receives operating power only from the secondary bias supply.
