The LM2575-3.3WT from Microchip Technology is a monolithic integrated circuit designed as a simple 1A step-down (buck) switching regulator. This fixed output version provides a stable 3.3V.
Key electrical specifications include a wide input voltage range from 4V to 40V, a guaranteed 1A output current, and a fixed switching frequency of 52kHz. The device includes internal frequency compensation and a fixed-frequency oscillator, simplifying external component requirements. It offers an efficiency replacement for linear regulators, often eliminating the need for a heat sink.
Packaged in a TO-220-5 configuration, this regulator is suitable for through-hole mounting. It features thermal shutdown and cycle-by-cycle current limiting for protection under fault conditions. The LM2575 series is designed for ease of use in switch-mode power supply designs, requiring a minimum number of external components.
Applications include simple high-efficiency step-down regulators, pre-regulators for linear regulators, and on-card switching regulators. The output voltage is guaranteed to ±3% tolerance within specified input voltages and load conditions.
