3 Description
The LM25185 is a primary-side regulated (PSR)
flyback controller with high efficiency over a wide
input voltage range of 4.5 V to 42 V. The
isolated output voltage is sampled from the primaryside
flyback voltage, eliminating the need for an
optocoupler, voltage reference, or third winding from
the transformer for output voltage regulation.
