1 -A简单的降压开关稳压器 1-A SIMPLE STEP-DOWN SWITCHING VOLTAGE REGULATORS

The is a step-down Switching Voltage Regulator provides all the active functions needed for a step-down buck switching regulator in an integrated circuit. It requires four to six external components for operation. It has an integrated switch capable of delivering 1A of load current, with excellent line and load regulation. The device also offers internal frequency compensation, a fixed-frequency oscillator, cycle-by-cycle current limiting and thermal shutdown. In addition, a manual shutdown is available via an external ON/OFF pin. It represents superior alternatives to popular three-terminal linear regulators. Due to its high efficiency, it is significantly reduce the size of the heat sink and, in many cases, no heat sink is required. It is optimized for use with standard series of inductors available from several different manufacturers. It is greatly simplify the design of switch-mode power supplies.
