LM2596HV

LM2596HV 60V 3A 150kHz Step-Down Voltage Regulator GENERAL DESCRIPTION The LM2596HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) 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. Available in a standard 5-lead TO-220 package, 5-lead TO-263 surface mount package and SOP-8 package. External shutdown is included, featuring typically 30 μA standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown, and protection from output short for full protection under fault conditions. FEATURES  3.3V, 5V, 12V, and adjustable output versions  Adjustable version output voltage range, 1.2V to 57V  ±4% maximum over line and load conditions  Available in TO-220 and TO-263 packages and SOP-8 (for lload<2A)  Guaranteed 3A output load current  Input voltage range up to 60V  Requires only 4 external components  Excellent line and load regulation specifications  150 kHz fixed frequency internal oscillator  Low power standby mode, Istb typically 30 μA  High efficiency  Thermal shutdown and current limit protection  Output short protection by reduction of frequency by 3 times. APPLICATIONS  Simple high-efficiency step-down (buck) regulator  On-card switching regulators  Efficient pre-regulator for linear regulators PIN CONFIGU...
