LM2675N-5.0/NOPB Datasheet PDF - TI

●The LM2675N-5.0/NOPB is a Step-down Regulator built with a LMDMOS process. It provides all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load current with excellent line and load regulation. It requires a minimum number of external components, these regulators are simple to use and include patented internal frequency compensation (Patent Nos. 5,382,918 and 5,514,947) and a fixed frequency oscillator. The LM2675 series operates at a switching frequency of 260kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Because of its very high efficiency (>90%), the copper traces on the printed circuit board are the only heat sinking needed. Other features include a guaranteed ±1.5% tolerance on output voltage within specified input voltages and output load conditions and ±10% on the oscillator frequency. External shutdown is included, featuring typically 50µA stand-by current.
