Step-Down Voltage Regulator, LM2675N-ADJ/NOPB, Texas Instruments
The LM2675N-ADJ/NOPB regulator is a monolithic integrated DC-DC converter circuit built with an LMDMOS process. This regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 1 A load current with excellent line and load regulation. Requiring a minimum number of external components, this regulator is simple to use and includes patented internal frequency compensation and a fixed-frequency oscillator. The LM2675N-ADJ/NOPB regulator operates at a switching frequency of 260 kHz, thus allowing smaller-sized filter components than what is needed with a lower frequency switching regulator. Because of the very high efficiency (> 90%), the copper traces on the printed-circuit board are the only heat sinking needed.
Features
- Efficiency up to 96%
- Requires only five external components
- TTL shutdown capability, low power standby mode
- Thermal shutdown and current limit protection
Applications
- Simple high efficiency (> 90%) step-down (buck) regulators
- Efficient preregulator for linear regulators
