Texas Instruments LM22672 1A SIMPLE SWITCHER?, Step-Down Voltage Regulator with Adjustable Frequency LM22672MR-ADJ/NOPB

The LM22672MR-ADJ/NOPB is a step-down voltage regulator from Texas Instruments, designed to provide efficient power conversion with a wide input voltage range of 4.5 V to 42 V. It is capable of delivering up to 1 A of load current and features an internally compensated voltage mode control, which simplifies design by eliminating the need for external compensation components. The regulator supports both adjustable output voltage down to 1.285 V and a fixed 5 V output option, with a feedback reference accuracy of ¬±1.5%. The device operates at a default switching frequency of 500 kHz, which can be adjusted between 200 kHz and 1 MHz for flexibility in design. It is stable with low ESR ceramic capacitors, ensuring high efficiency, typically exceeding 90%. The LM22672MR-ADJ/NOPB also includes features such as a precision enable input, adjustable soft-start, thermal shutdown, and current limiting for protection against overloads. It is rated for operation in a junction temperature range of -40¬8C to 125¬8C, making it suitable for various industrial and automotive applications. The package type is an 8-pin SO PowerPAD, facilitating thermal management and PCB integration.
