The UCC28C40DG4 is an integrated circuit (IC) component designed for controlling and regulating switch-mode power supplies (SMPS). It is particularly suitable for offline power supplies and other applications that require high performance and efficiency.
Key Features:
1. Wide Input Voltage Range: The UCC28C40DG4 can accommodate input voltages ranging from 4.5V to 28V, making it compatible with a wide range of power sources.
2. Oscillator Frequency Range: It operates at a relatively high frequency range of 100kHz to 1MHz, allowing for fast response times and efficient power conversion.
3. Integrated High-Voltage Startup: The IC incorporates a high-voltage startup circuit, eliminating the need for an external soft-start capacitor.
4. Adjustable Overcurrent Protection: The UCC28C40DG4 supports adjustable overcurrent protection, providing flexibility and safety in various load conditions.
5. Cycle-by-Cycle Peak Current Limiting: It incorporates a cycle-by-cycle peak current limit feature that ensures output current regulation and prevents overloading.
6. Under-Voltage Lockout (UVLO) Protection: The IC includes UVLO protection, which prevents improper operation when the input voltage is too low.
7. Precision Reference Voltage: A precision reference voltage of 2.5V is integrated into the IC, ensuring accurate regulation and control
