3A降压开关稳压器
The is a step-down Voltage Regulator provides all of the active functions for a step-down buck switching regulator capable of driving up to 3A loads with excellent line and load regulation characteristics. High efficiency >90% is obtained through the use of a low on-resistance DMOS power switch. The SIMPLE SWITCHER concept provides for a complete design using a minimum number of external components. A high fixed frequency oscillator 260KHz allows the use of physically smaller sized components. A family of standard inductors for use with the LM2676 are available from several manufacturers to greatly simplify the design process. The LM2676 series also has built in thermal shutdown, current limiting and an on/off control input that can power down the regulator to a low 50µA quiescent current standby condition. The output voltage is ensured to a ±2% tolerance. The clock frequency is controlled to within a ±11% tolerance.
