Texas Instruments LM5181/LM5181-Q1 Primary-Side Regulated (PSR) Flyback Converters come with high efficiency over a wide input voltage range of 4.5V to 65V. The isolated output voltage is sampled from the primary-side flyback voltage, eliminating the need for an optocoupler, voltage reference, or third winding from the transformer for output voltage regulation. The high level of integration results in a simple, reliable, and high-density design with only one component crossing the isolation barrier. Boundary conduction mode (BCM) switching enables a compact magnetic solution and better than ±1.5% load and line regulation performance. An integrated 100V power MOSFET provides output power up to 4W with enhanced headroom for line transients. The Texas Instruments LM5181/LM5181-Q1 flyback converters are available in an 8-pin, 4mm × 4mm, thermally-enhanced WSON package with a 0.8mm pin pitch. The LM5181-Q1 devices are AEC-Q100 qualified for automotive applications.
