LM2672M-3.3

电源转换器高效率1A降压型稳压器与特点 Power Converter High Efficiency 1A Step-Down Voltage Regulator with Features

The is a SIMPLE SWITCHER® Power Converter Step-down Voltage Regulator provides all the active functions for a step-down buck switching regulator, capable of driving a 1A load with excellent line and load regulation. This regulator is available in fixed output voltages of 3.3V version and requiring a minimum number of external components, this regulator is simple to use and include patented internal frequency compensation, a fixed-frequency oscillator, soft-start and frequency synchronization. The regulator 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 high efficiency, the copper traces on the printed circuit board are normally the only heat sinking needed. Other features include a ensured ±1.5% tolerance on output voltage within specified input voltages and output load conditions and ±10% on the oscillator frequency.
