LM5181QNGURQ1, Switching Voltage Regulators Automotive 65-VIN no-opto flyback DC/DC converter with 100-V, 0.75-A integrated MOSFET 8-WSON -4
Semiconductors\Power Management ICs\Voltage Regulators & Voltage Controllers\Switching Voltage RegulatorsLM5181/LM5181-Q1 PSR Flyback Converters 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 x 4mm, thermally-enhanced WSON package with a 0.8mm pin pitch. The LM5181-Q1 devices are AEC-Q100 qualified for automotive applications.
