With 1500 Vdc (1000 Vrms) isolation and a small pack-
age size, the LPD5030V series is ideal for use in high
density isolated circuit applications.
Functional Safety Listed by UL. Functional
insulation class for TNV-1 to SELV applica-
tions. Functional insulation with a maximum
60 Vdc, 42.4 V peak input/output voltages with working
voltages up to 210 Vdc. (Report #E219588-A6)
These miniature transformers provide tight coupling, high
inductance and excellent current handling.
They can be used as
• Flyback transformers
• Coupled inductors in SEPIC applications
• Common mode filter chokes.
