The LM22671QMR-ADJ/NOPB is a step-down (buck) voltage regulator capable of handling input voltages from 4.5 V to 42 V and providing an adjustable output voltage as low as 1.285 V. It supports a maximum load current of 500 mA and features an internally compensated voltage mode control, which simplifies design by eliminating the need for external compensation components. The device operates with a default switching frequency of 500 kHz, which can be adjusted between 200 kHz and 1 MHz for flexibility in design. This regulator is designed for high efficiency, exceeding 90%, and is stable with low ESR ceramic capacitors. It includes features such as a precision enable pin, adjustable soft-start, and built-in thermal shutdown and current limiting for protection against overloads. The LM22671QMR-ADJ/NOPB is housed in an 8-pin SO PowerPAD package and is rated for operation in a temperature range of -40¬8C to +125¬8C, making it suitable for automotive and industrial applications.
