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-263-5Product OverviewThe LM2576HVS-5.0/NOPB is a SIMPLE SWITCHER® low component count Step-downRegulator provides all the active functions for a step-down (buck) switchingregulator, capable of driving 3A load with excellent line and load regulation.This regulator is available in fixed output voltages of 5V version and requiringa minimum number of external components, this regulator is simple to use andinclude internal frequency compensation and a fixed-frequency oscillator. TheLM2576 series offers a high-efficiency replacement for popular three-terminallinear regulators. It substantially reduces the size of the heat sink and insome cases no heat sink is required. A standard series of inductors optimizedfor 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 components52kHz Fixed frequency internal oscillatorTTL shutdown capability, low power standby modeHigh efficiencyUses readily available standard inductorsThermal shutdown and current limit protectionP+ Product enhancement testedApplicationsPower ManagementProduct InformationTopology: Buck (Step Down)Input Voltage Min: 4VInput Voltage Max: 60VDC / DC Converter IC Case: TO-263 (D2PAK)No. of Pins: 5PinsOutput Current: 3AOutput Voltage Nom: 5VSwitching Frequency: 52kHzOperating Temperature Max: 125°C
