Introduction
The LM2575 is a 50KHz fixed-frequency PWM DC-DC switching regulator capable of delivering 2A output current, featuring high efficiency, low ripple, and excellent line and load regulation. The device operates in PWM modulation mode with a linearly adjustable duty cycle ranging from 0 to 100%. It integrates a fixed-frequency oscillator and frequency compensation module, requiring minimal external components for ease of use. Additionally, the chip incorporates enable control with hysteresis, over-temperature protection, overcurrent protection, and secondary overcurrent protection. When secondary overcurrent protection is triggered, the built-in frequency reduction function reduces the operating frequency from 150KHz to 50KHz.
Features
- 4.5V to 40V input voltage range
- Fixed regulated output at 3.3V, 5V, 12V and adjustable version with output range 1.23V to 37V
- Duty cycle adjustable range 0~100%
- Minimum saturation voltage drop 1.5V
- 50KHz fixed operating frequency
- 2A output current capability
- ON/OFF hysteresis switching function
- Built-in over-temperature protection and over-current protection
- Built-in frequency compensation
- High efficiency, high line regulation and load regulation
Applications
- LCD monitors
- LCD TVs
- Digital photo frames
- TV set-top boxes
- Modems
