3-V to 6-V DC input, 5-V/0.5-A, 1-MHz isolated flyback reference design


Design files


This reference design uses the TPS61175 boost converter to drive a flyback power stage. With its integrated MOSFET, the TPS61175 reduces the circuit complexity and footprint. In addition, operating at 1MHz reduces the size of the passive components.
