LM22676MRX-ADJ/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LM22676MRX-ADJ/NOPB is a monolithic, synchronous step-down converter optimized for high-efficiency, low-noise operation in applications demanding precise voltage regulation. This specific part number denotes a surface-mount device in a thermally enhanced 16-pin QFN (quad flat no-lead) package, lacking integrated feedback (ADJ) and omitting a power good output (NOPB). It operates from an input voltage range of 4.5V to 24V, providing an adjustable output voltage down to 0.8V, making it suitable for a wide range of applications. The device features internal compensation, enabling simplified design without external components for many applications. It achieves high efficiency through synchronous rectification and utilizes a constant frequency current mode control architecture, minimizing output voltage ripple. Typical applications include powering high-precision analog circuits, powering microprocessors needing tight voltage regulation, and point-of-load converters in distributed power architectures where low noise and high efficiency are critical. The LM22676MRX-ADJ/NOPB’s adjustable output and compact form factor make it a versatile solution for space-constrained designs requiring precise and efficient voltage regulation in demanding environments. Note the absence of a power good pin necessitates alternative power sequencing methods.
