The LM25007SDX/NOPB is a non-synchronous buck regulator designed for step-down voltage conversion with an input voltage range of 9V to 42V and a guaranteed output current of 0.5A. It features an integrated 0.74Oc N-channel MOSFET switch and operates at frequencies up to 800kHz, utilizing a constant on-time architecture that eliminates the need for external control loop compensation. The device is capable of ultra-fast transient response and includes Vin feed forward for maintaining a consistent operating frequency. The output voltage can be set from 2.5V to over 30V, and the regulator incorporates intelligent current limit protection, thermal shutdown, and external shutdown control. It is available in compact VSSOP-8 and thermally enhanced WSON-8 packages, making it suitable for applications in distributed rail systems, automotive electronics, industrial systems, and LED drivers. The LM25007SDX/NOPB is rated for operation over a temperature range of -40¬8C to 125¬8C, ensuring reliability in various environments.
