LM2575 datasheet

Description :

The LM2575 greatly simplifies the design of switching power supplies by conveniently providing all the active functions needed for a step-down (buck) switching regulator in an integrated circuit. Accepting a wide input voltage range and available in an adjustable output version, the LM2575 has an integrated switch capable of delivering 1 A of load current, with excellent line and load regulation. The device also offers internal frequency compensation, a fixed-frequency oscillator, cycle-by-cycle current limiting, and thermal shutdown. In addition, a manual shutdown is available via an external ON/OFF pin.

Features :

• Adjustable With a Range of 1.23 V to 37 V and ±4% Regulation (Max) Over Line, Load, and Temperature Conditions

• Specified 1-A Output Current

• Wide Input Voltage Range…4.75 V to 40 V

• Uses Readily Available Standard Inductors

• 52-kHz (Typ) Fixed-Frequency Internal Oscillator

• TTL Shutdown Capability With 50-µA (Typ) Standby Current

• High Efficiency…as High as 88% (Typ)

• Thermal Shutdown and Current-Limit Protection With Cycle-by-Cycle Current Limiting

• For the Full Offering of Voltages (Including Fixed-Output Options) and Packages(Including TO-263), see TL2575 Datasheet

Applications :

• Simple High-Efficiency Step-Down (Buck) Regulator

• Pre-Regulator for Linear Regulators

• On-Card Switching Regulators

• Positive-to-Negative Converter (Buck-Boost)
