Reference Designs
10-VDC to 30-VDC input PSR flyback converter with dual-output reference design
Texas Instruments
This reference design provides two isolated voltages (6 V at 200 mA: 12 V at 200 mA) from a DC-input supply (10 V - 30 V). By means of zero ohm resistors: a flexible transformer can be configured to change the turns ratio and output voltages without any layout change. The converter enables an isolated DC/DC solution with high density and low component count. No auxiliary transformer winding is required and a 100-V rated primary-side switch is integrated.
Features
- Provides compact solution due to elimination of optocoupler and transformer auxiliary windingProgrammable soft start limits the inrush current drawn by the power supplyRated for up to 200 mA of load currentResistor divider to EN/UVLO to faciltate programmable input voltage UVLOTested design with available design files and test reportFlexible transformer used for easy output voltage change
