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

Para corrientes mayores a 2A se recomienda colocar disipador o forzador

Output current is greater than 2A (or output power greater than 10W) to work long hours, please add heat sink.
