Lm2596 Voltage Regulators - China

FEATURES DESCRIPTION

23 The LM2596 series of regulators are monolithic • 3.3V, 5V, 12V, and Adjustable Output Versions

integrated circuits that provide all the active functions

• Adjustable Version Output Voltage Range, for a step-down (buck) switching regulator, capable of

1.2V to 37V ±4% Max Over Line and Load driving a 3A load with excellent line and load

Conditions regulation.

These devices are available in fixed output

• Available in TO-220 and TO-263 Packages voltages of 3.3V, 5V, 12V, and an adjustable output

version.

• Ensured 3A Output Load Current

• Requiring a minimum number of external Input Voltage Range Up to 40V

components, these regulators are simple to use and • Requires Only 4 External Components include internal frequency compensation, and a

• Excellent Line and Load Regulation fixed-frequency oscillator.

Specifications

The LM2596 series operates at a switching frequency

• 150 kHz Fixed Frequency Internal Oscillator of 150 kHz thus allowing smaller sized filter

• TTL Shutdown Capability components than what would be needed with lower

• Low Power Standby Mode, I

frequency switching regulators.

Available in a

Q Typically 80 μA

standard 5-lead TO-220 package with several

• High Efficiency different lead bend options, and a 5-lead TO-263

• Uses Readily Available Standard Inductors surface mount package.

• Thermal Shutdown and Current Limit A standard series of inductors are available from

Protection several different manufacturers optimized for use with

the LM2596 series.

This feature greatly simplifies the

APPLICATIONS design of switch-mode power supplies.

• Simple High-Efficiency Step-Down (Buck) Other features include a ensured ±4% tolerance on

Regulator output voltage under specified input voltage and

output load conditions, and ±15% on the oscillator • On-Card Switching Regulators

frequency.

External shutdown is included, featuring

• Positive to Negative Converter typically 80 μA standby current.

Self protection

features include a two stage frequency reducing

current limit for the output switch and an over

temperature shutdown for complete protection under

fault conditions.
