LM2672MX-ADJ/NOPB .

Импульсный понижающий DC-DC стабилизатор, регулируемый, 260кГц, 6.5В-40В вход, 1.2В-57В/1А выход.

The LM2672MX-ADJ/NOPB is a SIMPLE SWITCHER® low component count Step-down Regulator 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. Requiring a minimum number of external components, this regulator is simple to use and include patented internal frequency compensation (patent nos. 5,382,918 and 5,514,947), fixed frequency oscillator, external shutdown, soft-start and frequency synchronization. The LM2672 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. A family of standard inductor for use with the LM2672 is available from several different manufacturers.
