Description

Electronic Component Model: NCP1203D60 is a PWM Current-Mode Controller used in universal off-line supplies. It is designed to provide standby and short circuit protection. This component is available in SOIC-8 or PDIP-8 package. With its compact size, it is an excellent candidate to replace UC384X devices. The NCP1203 utilizes SMARTMOS™ Very High Voltage Technology, allowing the implementation of complete off-line AC-DC adapters, battery chargers, and high-power SMPS with minimal external components. The controller operates at a fixed switching frequency of 40 kHz, 60 kHz, or 100 kHz, and features a high-voltage startup FET for a clean and lossless startup sequence. Its current-mode control ensures good audio susceptibility and pulse-by-pulse control.
