Texas Instruments (LM2576HVS-5.0/NOPB .) Buck Switching Regulator

Buck (Step Down) Switching Regulator, Fixed, 4V-60V In, 5V And 3A Out, 52 kHz, TO-263-5 Product Overview The LM2576HVS-5.0/NOPB is a SIMPLE SWITCHER® low component count Step-down Regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving 3A 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, this regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink and in some cases no heat sink is required. A standard series of inductors optimized for use with the regulator are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. Requires only 4 external components 52kHz Fixed frequency internal oscillator TTL shutdown capability, low power standby mode High efficiency Uses readily available standard inductors Thermal shutdown and current limit protection P+ Product enhancement tested Applications Power Management Product Information Topology: Buck (Step Down) Input Voltage Min: 4V Input Voltage Max: 60V DC / DC Converter IC Case: TO-263 (D2PAK) No. of Pins: 5Pins Output Current: 3A Output Voltage Nom: 5V Switching Frequency: 52kHz Operating Temperature Max: 125°C
