The NCP1203D60DR2G from ON Semiconductor is a versatile and efficient PWM current-mode controller designed for high-performance power supply systems. This compact and reliable component is ideal for a wide range of applications, including AC-DC adapters, offline battery chargers, and auxiliary power supplies.

Key Features

• Current-Mode Control: Provides fast transient response and excellent loop stability, making it suitable for demanding applications.
• Fixed 60kHz Switching Frequency: Offers a good balance between efficiency and component size, reducing electromagnetic interference (EMI) and allowing for smaller passive components.
• Internal Ramp Compensation: Minimizes the need for external components and simplifies the design process.
• Auto-Recovery Overload Protection: Ensures long-term reliability by protecting the device and the system from overcurrent conditions.
• Low Startup Current: Reduces power consumption and increases efficiency during the initial power-up phase.
• Frequency Jittering: Reduces EMI and allows for a cost-effective design by minimizing the need for additional EMI filtering.
• Soft-Start: Limits inrush current during startup, enhancing system safety and extending the life of the power supply.
• Under-Voltage Lockout (UVLO): Prevents the device from operating at insufficient supply voltages, which could lead to unpredictable behavior.
