LM5185/LM5185-Q1 PSR Flyback Controller

Texas Instruments LM5185/LM5185-Q1 Primary-Side Regulated (PSR) Flyback Controller is a 100V_IN DC/DC controller with low I_Q and low EMI. This controller comes with a PSR with a high efficiency over a 4.5V to 100V wide input voltage range. The LM5185-Q1 flyback controller features a high level of integration, resulting in a simple, reliable, and high-density design with only a transformer crossing the isolation barrier. The Boundary Conduction Mode (BCM) switching enables a compact magnetic design and better than ±1.5% load and line regulation performance. The LM5185/LM5185-Q1 controller includes an integrated high-current MOSFET gate driver that extends the power range from less than 1W to more than 50W. Typical applications include HVAC compressors, interior heater modules, generic isolated bias power rails for industrial and telecom systems, and generic IGBT, MOSFET, GaN, and SiC gate drivers.
