LM2599S-ADJ/NOPB Datasheet PDF - TI

●The LM2599S-ADJ/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 3A load with excellent line and load regulation. It is a member of the LM259x family, with additional supervisory and performance features added. Requiring a minimum number of external components, this regulator is simple to use and include internal frequency compensation, improved line and load specifications, fixed-frequency oscillator, shutdown and soft-start, error flag delay and error flag output. The LM2599 series operates at a switching frequency of 150kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. A standard series of inductors (both through-hole and surface-mount types) are available from several different manufacturers optimized for use with the LM2599 series. This feature greatly simplifies the design of switch-mode power supplies.
