LM2594 Datasheet PDF

●The LM2594M-ADJ is a SIMPLE SWITCHER® Power Converter 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 an adjustable output voltage version and requiring a minimum number of external components, this regulator is simple to use and include internal frequency compensation, a fixed-frequency oscillator and improved line and load regulation specifications. The regulator operates at a switching frequency of 150kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Because of its high efficiency, the copper traces on the printed circuit board are normally the only heat sinking needed. Other features include ±4% tolerance on output voltage under all conditions of input voltage and output load conditions and ±15% on the oscillator frequency.

● 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

●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.
