Overview
3845 is a current-mode PWM IC designed for switching power supplies. Compared to voltage-mode control, it offers significant advantages in load transient response and line regulation. The device is available in SOP8 and DIP8 packages.
Key features
- Built-in undervoltage lockout circuit
- Low startup current (typical 60μA)
- Stable internal reference voltage source
- High-current push-pull output (drive current up to 1A)
- Operating frequency up to 500kHz
- Automatic negative feedback compensation circuit
- Double pulse suppression function
- Excellent load transient response
