LM2576HVS-12/NOPB Datasheet PDF - TI

●The LM2576HVS-12/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 12V 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

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
