MC44608P75

The MC44608P75 is an integrated circuit (IC) component used in power supply applications. It is part of the MC446xx family of ICs manufactured by ON Semiconductor. This particular IC is designed to be used as a controller for offline, non-isolated power supplies. Key features of the MC44608P75 include: 1. High Voltage Start-Up Circuit: The IC incorporates a high voltage start-up circuit that enables it to operate directly from the rectified mains supply without requiring an additional startup circuit. 2. Current Mode Control: The MC44608P75 utilizes a current mode control technique for regulating the output voltage. This allows for better dynamic response and stability in power supplies. 3. Internal Oscillator: The IC incorporates an internal oscillator that operates at a fixed frequency of 25 kHz. This eliminates the need for external components to generate the timing signals required for the power supply. 4. Soft Start: The IC features a soft start function that allows for a gradual increase in output voltage during startup. This prevents overshoots and transients, thereby protecting the power supply and connected components. 5. Pulse Width Modulation (PWM): The IC employs a pulse width modulation technique for controlling the output voltage based on the current mode control principle. This ensures efficient power transfer and regulation. 6. Protection Mechanisms: The MC44608P75 offers various protection features, including overvoltage protection, overcurrent protection, and thermal shutdown
