Texas Instruments LM25184/LM25184-Q1 PSR Flyback DC/DC Converter is a primary-side regulated (PSR) flyback converter 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. 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 15W with enhanced headroom for line transients.
The Texas Instruments LM25184 simplifies the implementation of isolated DC/DC supplies with optional features to optimize performance for the target end equipment. The output voltage is set by one resistor, while an optional resistor improves output voltage accuracy by negating the thermal coefficient of the flyback diode voltage drop. Additional features include an internally-fixed or externally-programmable soft-start, precision enable input with hysteresis for adjustable line UVLO, hiccup-mode overload protection, and thermal shutdown protection with automatic recovery. The LM25184-Q1 devices are AEC-Q100 qualified for automotive applications.
