1 ,简单的一个步骤,降压型开关稳压器 1-A SIMPLE STEP DOWN SWITCHING VOLTAGE REGULATOR
The LM2575 device greatly simplifies the design of switching power supplies by conveniently providing all the active functions needed for a step-down buck switching regulator in an integrated circuit. Accepting a wide input voltage range and available in an adjustable output version, the LM2575 has an integrated switch capable of delivering 1 A 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 through an external ON/OFF pin.
The LM2575 represents a superior alternative to popular three-terminal linear regulators. Due to its high efficiency, it significantly reduces the size of the heat sink and, in many cases, no heat sink is required. Optimized for use with standard series of inductors available from several different manufacturers, the LM2575 greatly simplifies the design of switch-mode power supplies by requiring a minimal addition of only four to six external components for operation.
The LM2575 is characterized for operation over the virtual junction temperature range of 40°C to 125°C.
