Overview
UC2844 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.
Applications
- Switching regulator with any polarity
- Transformer-coupled DC-DC converter
Key features
- Internal undervoltage lockout circuit
- Low startup and operating current (typical 0.26mA)
- Maximum duty cycle control
- High-current totem-pole output (drive current up to 1A)
- Operating frequency: 500kHz
- Automatic feed-forward compensation
- Double pulse suppression
- Enhanced load response characteristics
