Flyback Transformers for Microchip Grid-Connected Solar Micro Inverter

• Developed for Microchip for their Grid-Connected Solar Micro Inverter using dsPIC
• For 220 Vac applications, KA4823-BL has been replaced by KA4823-CL, which has a higher SRF and higher efficiency.
• 3000 Vrms, one minute primary to secondary isolation
• Listed on Bill of Material for Reference Design AN1338
• Input voltage: 22 Vdc – 55 Vdc
• RoHS-compliant. Tin-silver (96.5/3.5) over tin over copper over phos bronze terminations

1	Inductance is for the primary, measured at 150 kHz, 0.1 Vrms.
2	DCR is with the secondary windings connected in parallel.
3	Leakage inductance is for the three windings  of the primary with the secondary windings shorted.
4	Turns ratios are with the primary and secondary windings connected in parallel.
5	Isat: DC current at which the inductance drops 10% (typical) from its value without current.
6	Ambient temperature range:	–40°C to +85°C
7	Storage temperature range:	Component: –40°C to +85°C Packaging trays: –40°C to +80°C
8	Electrical specifications at 25°C.
