The LM22671MR-ADJ is a step-down (buck) switching regulator capable of delivering up to 500 mA of output current. It operates over a wide input voltage range of 4.5V to 42V and achieves high efficiency exceeding 90% through the use of a low ON-resistance N-channel MOSFET. This adjustable version allows output voltages as low as 1.285V, making it versatile for various applications. The device features an internal fixed frequency oscillator operating at 500 kHz, which can be adjusted or synchronized to an external clock up to 1 MHz. It includes built-in protections such as thermal shutdown and current limiting, along with a precision enable pin for low quiescent current standby operation. The LM22671MR-ADJ is designed to be stable with low ESR ceramic capacitors and supports adjustable soft-start functionality. This regulator is suitable for applications in industrial control, telecom and datacom systems, embedded systems, and automotive electronics. It is packaged in an 8-lead PSOP-8 format with an exposed pad for improved thermal performance.
