Visão Geral
Description
The LM22675MR-5.0 is a 5.0V, 3A step-down (buck) switching regulator from Texas Instruments. It features high efficiency (up to 91%), a wide input range (4.5V to 42V), and fixed-frequency PWM operation (500 kHz) for stable output.
Key benefits include:
- Integrated MOSFET for compact designs.
- Thermal shutdown & current limiting for protection.
- Low standby current (~1 mA) for power-sensitive applications.
Ideal for industrial, automotive, and telecom systems requiring efficient voltage conversion. The TO-263-7 package aids heat dissipation.
For details, refer to the datasheet or TI’s product page.
