The Texas Instruments LM5027SQX-1-NOPB is a highly integrated controller IC designed for forward converter topologies. This device facilitates efficient step-up or step-down DC-DC conversion with an isolation-capable positive output. Key control features include frequency control, ramp generation, and soft-start for optimized power delivery. The LM5027SQX-1-NOPB supports dual switching frequencies, 200kHz and 490kHz, and boasts a maximum duty cycle of 90%. It is equipped with a synchronous rectifier for enhanced efficiency and offers multiple output configurations, driving up to three outputs. Operating within a wide voltage supply range of 13V to 90V and a junction temperature range of -40°C to 125°C, this component is suitable for applications in industrial power supplies, automotive systems, and telecommunications infrastructure. The component is supplied in a 24-WFQFN exposed pad package, presented on tape and reel (TR).
