Texas Instruments LM3100
The LM3100 Synchronously Rectified Buck Converter features all functions needed to implement a highly efficient, cost effective buck regulator capable of supplying 1.5 A to loads with voltages as low as 0.8 V. The LM3100 is designed to work exceptionally well with ceramic and other very low ESR output capacitors. The Constant ON-Time (COT) regulation scheme requires no loop compensation, results in fast load transient response, and simplifies circuit implementation.- Max Voltage : 5V
- Max Operating Temp : 70°C
- Min Operating Temp : -20°C
