Quality Control: Learn More
The Microchip Technology LM2575-3-3BN is a monolithic integrated circuit providing all the necessary functions for a plus voltage step-down (buck) switching regulator. This 1A output current device features a fixed 3.3V output voltage and operates with a switching frequency of 52kHz. Its robust design supports input voltages from 4V to 40V, with an internal oscillator that can be synchronized to an external clock up to the device's rated frequency. The LM2575-3-3BN is available in a 16-DIP (0.300", 7.62mm) package, suitable for through-hole mounting. This component is widely utilized in power supply applications across consumer electronics, industrial control systems, and telecommunications infrastructure. The device includes overcurrent protection, thermal shutdown, and a flyback diode internal to the IC, simplifying external component requirements.
