PRODUCTION DATA
The turns ratio and primary inductance are important parameters to consider in a flyback transformer. The turns ratio act to limit the max duty cycle and reduce stress on the secondary components while the primary inductance sets the current ripple. In CCM operation, the higher inductance allows for a reduced current ripple which can help with EMI performance and noise.
For primary-side regulated flyback converters, the transformer construction is important to maintain good regulation on the secondary output. It is recommended to use LDT0950 for 12-V applications.
