The LM5180QNGURQ1 from Texas Instruments is an automotive-grade PSR (Primary-Side Regulation) flyback DC/DC converter designed for reliable and rugged applications. It boasts a wide input voltage range from 4.5 V to 65 V and integrates a 100-V, 1.5-A power MOSFET, eliminating the need for an opto-coupler or transformer auxiliary winding for output voltage regulation.
This converter operates with a switching frequency between 12 kHz and 350 kHz, offering a maximum duty cycle of 82%. Key features include enable functionality, light load efficiency, pre-bias soft start, and adjustable UVLO (Under-Voltage Lockout). It provides ±1.5% total output regulation accuracy and has an operating junction temperature range of -40°C to +150°C.
The LM5180QNGURQ1 is housed in a compact 8-WSON (4x4 mm) package, suitable for surface mounting. Its design emphasizes integration to reduce solution size and cost, while also ensuring low EMI operation to meet CISPR 25 standards. The device is AEC-Q100 qualified for automotive applications.
This converter is functional safety-capable and includes protection features such as input UVLO and thermal shutdown, along with hiccup-mode overcurrent fault protection. An external bias option is available for improved efficiency.
