The LM5085MM/NOPB is a high voltage flyback controller integrated circuit (IC) manufactured by Texas Instruments. It is specifically designed for applications that require an isolated output and input voltage up to 75V. This IC provides a cost-effective and efficient solution for flyback converter topologies.
One prominent feature of the LM5085MM/NOPB is its wide input voltage range, which allows it to operate in various applications, including industrial, automotive, and telecom systems. This versatility makes it suitable for a wide range of power supply designs.
The IC incorporates various protection features to ensure system reliability. It includes an overvoltage protection (OVP) circuit that monitors the output voltage and provides accurate feedback control. This safeguards the system from voltage surges or spikes, preventing potential damage to downstream components.
Additionally, the IC offers a cycle-by-cycle current limit mechanism, preventing excessive load currents. It ensures safe operation by cutting off the switching cycle when the current limit is exceeded, protecting the IC and the connected devices.
The LM5085MM/NOPB utilizes a unique constant on-time control mode that enables fast transient response and simplifies external compensation. This control mechanism eliminates the need for additional loop compensation components, leading to cost savings and a simplified design process.
The IC incorporates a wide range of features to enhance overall performance. It provides a high switching frequency of up to 1 MHz, enabling the design of compact and efficient power converters
