NCP1207APG PWM Current-Mode Controller DIP-8 ON Semiconductor

The NCP1207APG from ON Semiconductor is a high-performance PWM controller designed for quasi-resonant flyback converters. Its Dynamic Self-Supply (DSS) feature allows the controller to operate without an auxiliary winding, simplifying transformer design and reducing component count.​

Key Features:

• Quasi-resonant (QR) current-mode controller for flyback converters
• Dynamic Self-Supply (DSS) eliminates the need for an auxiliary winding
• Adjustable skip-cycle mode for enhanced light-load efficiency
• Integrated overvoltage protection (OVP) with latch-off functionality
• Auto-recovery overcurrent protection (OCP)
• Internal 1 ms soft-start to minimize inrush current​

Additional Specifications:

• Package Type: DIP-8
• Supply Voltage: 20 V
• Current: 500 mA
• Type: PWM Current-Mode Controller
