| Description | The LM5009MM/NOPB is a highly integrated step-down (buck) switching regulator developed by Texas Instruments, designed for efficient power conversion in high-voltage industrial and embedded systems. It incorporates an internal N-channel MOSFET, enabling a compact and low-component-count solution for DC-DC conversion. This device supports a wide input voltage range from 9.5V to 95V, making it suitable for applications powered from unregulated or high-voltage sources such as 12V, 24V, and 48V systems. It can deliver up to 150mA output current, providing stable power for control circuits and auxiliary supplies. The LM5009MM/NOPB features a constant on-time (COT) control architecture, which maintains a nearly constant switching frequency and eliminates the need for complex loop compensation, simplifying design and improving transient response performance. It supports switching frequencies exceeding 600kHz, allowing the use of smaller external components. The output voltage is adjustable from 2.5V up to 85V, offering high flexibility for various system requirements. It also includes an internal startup regulator and VIN feedforward mechanism, ensuring stable operation across varying input conditions. Designed for reliability, the device integrates current limiting, thermal shutdown, and undervoltage lockout protection, ensuring safe operation under fault conditions and harsh environments. It operates over a wide temperature range of -40°C to +125°C, making it suitable for industrial-grade applications. Packaged in a compact 8-pin VSSOP surface-mount form factor, the LM5009MM/NOPB is ideal for space-constrained PCB designs while maintaining efficient thermal performance. The LM5009MM/NOPB is commonly used in industrial automation, telecom power supplies, automotive electronics, high-voltage DC systems, and distributed power architectures, where efficient and reliable voltage step-down conversion is required. |
