LM25180NGUR, Switching Voltage Regulators 42-Vin no-opto flyback converter with 65-V, 1.5-A integrated MOSFET 8-WSON -40 to 150

LM25180/LM25180-Q1 PSR Flyback Converter
Texas Instruments LM25180/LM25180-Q1 Primary-Side Regulated (PSR) Flyback Converter comes with high-efficiency over a wide input voltage range of 4.5V to 42V. The isolated output voltage is sampled from the primary-side flyback voltage, eliminating the need for an optocoupler, voltage reference, or a 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 65V power MOSFET provides output power up to 7W with enhanced headroom for line transients.
