- LM2575M-5.0/NOPB
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3754054-LM2575M-5.0/NOPB
- Description:
- IC REG BUCK 5V 1A 24-SOIC
- Datasheet:
- LM2575M-5.0/NOPB
Description
The LM2575 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2575 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in many cases no heat sink is required.
A standard series of inductors optimized for use with the LM2575 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies.
Other features include a specified ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, featuring 50 μA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
Features
3.3V, 5V, 12V, 15V, and Adjustable Output Versions
Adjustable Version Output Voltage Range, 1.23V to 37V (57V for HV Version) ±4% Max Over Line and Load Conditions
Specified 1A Output Current
Wide Input Voltage Range, 40V up to 60V for HV Version
Requires Only 4 External Components
52 kHz Fixed Frequency Internal Oscillator
TTL Shutdown Capability, Low Power Standby Mode
High Efficiency
Uses Readily Available Standard Inductors
Thermal Shutdown and Current Limit Protection
Applications
Simple High-Efficiency Step-Down (Buck) Regulator
Efficient Pre-Regulator for Linear Regulators
On-Card Switching Regulators
Positive to Negative Converter (Buck-Boost)
