LM2596-xx Switching Voltage Regulators
■The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use.
■The LM2596 series operates at a switching frequency of 150kHz. Available in standard 5-lead TO-220 package
■Other features include a guaranteed ± 4% tolerance on output voltage under specified input voltage and output load conditions. and ±15% on the oscillator frequency. External shutdown is included, featuring typically 100μA standby current. Self protection features include a two stage frequency reducing current limit for output switch and an over temperature shutdown for complete protection under fault conditions. The over temperature shutdown level is about 145°C with 59 hysteresis.
●Features:
■3.3V, 5V, 12V, and adjustable output versions
■Adjustable version output voltage range, 1.2V to 37V ±4% max over line and load conditions
■Guaranteed 3A output load current
■Input voltage range up to 40V
■Requires only 4 external components
■Excellent line and load regulation specifications
■150kHz fixed frequency internal oscillator
■TTL shutdown capability
■Low power standby mode,I-Q typically 100μA
■Thermal shutdown and current limit protection
