Texas Instruments LM2574N-5.0/NOPB Buck (Step Down) Switching Regulator Fixed 4V-40V In 5V And 0.5A Out 52 kHz DIP-8

The LM2574N-5.0/NOPB is a SIMPLE SWITCHER« Step-down Voltage Regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5A load with excellent line and load regulation. This regulator is available in fixed output voltages of 5V version and requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2574 series offers a high-efficiency replacement for popular three-terminal linear regulators. Because of its high efficiency, the copper traces on the printed circuit board are normally the only heat sinking needed. A standard series of inductors optimized for use with this regulator are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies.

• Requires only 4 external components
• TTL shutdown capability, low power standby mode
• High efficiency
• Uses readily available standard inductors
• Thermal shutdown and current limit protection
• Green product and no Sb/Br
