The LM2575HVT-15 from Texas Instruments is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It is capable of driving a 1A load with excellent line and load regulation, offering a fixed 15V output voltage. This regulator requires a minimum number of external components and includes internal frequency compensation and a fixed-frequency oscillator.
Key electrical specifications include a 1A output current, a 15V fixed output voltage, and a wide input voltage range up to 60V for the HV version. The device operates at a fixed frequency of 52kHz and offers ±4% maximum regulation over line and load conditions. It also features TTL shutdown capability for low power standby mode and thermal shutdown and current limit protection.
The LM2575 series provides a high-efficiency replacement for linear regulators, often eliminating the need for a heat sink. This specific part, the LM2575HVT-15, comes in a TO-220-5 package suitable for through-hole mounting.
This regulator is designed for ease of use, simplifying the design of switch-mode power supplies. It utilizes readily available standard inductors, further streamlining the design process.
