The Texas Instruments LM5027MHX-1-NOPB is a versatile DC-DC switching controller designed for forward converter topologies. This device offers flexible operation with selectable switching frequencies of 200kHz and 490kHz, supporting both step-up and step-down voltage conversion. Key control features include frequency control, ramp compensation, and soft-start functionality to ensure stable and efficient power delivery. The controller supports a wide input voltage range from 13V to 90V and features a high maximum duty cycle of 90%. Its output configuration is positive and isolation-capable, with the potential for three outputs. The LM5027MHX-1-NOPB is housed in a 20-HTSSOP package, suitable for surface mount applications, and operates across an industrial temperature range of -40°C to 125°C. This component is frequently utilized in power supply designs for industrial automation, automotive, and telecommunications sectors.
