Introduction
The LM2575 is a high-efficiency step-down DC-DC converter operating at a fixed 52KHz switching frequency, capable of delivering up to 3A of output current. Key features include low ripple, excellent line regulation, and load regulation. The device integrates a fixed-frequency oscillator and frequency compensation circuitry, simplifying circuit design. Its PWM control loop enables linear duty cycle adjustment from 0% to 100%. Additionally, it incorporates an enable function, output overcurrent protection, and an internal compensation module, helping to minimize external component count.
Features
- 4.5V to 40V wide input voltage range
- Output voltage adjustable from 1.23V to 37V
- Minimum dropout voltage: 1.5V
- Maximum switch current: 3A
- High efficiency
- TTL shutdown via enable pin
- Built-in thermal shutdown protection
- Available in fixed 5V, 12V output and adjustable output versions
- Maximum duty cycle: 100%
- Fixed 52KHz switching frequency
- Built-in power transistor
- Excellent line and load regulation
- Enable pin with hysteresis
Applications
- LCD TVs and displays
- Digital photo frames
- Set-top boxes
- Routers
- Communication equipment power supply
