NCP1203D60R2G SOP Power Controller IC – 60kHz Current Mode SMPS Switch with Skip-Cycle Mode

The NCP1203D60R2G SOP Power Controller IC is a compact, high-efficiency switch-mode controller designed to meet modern power supply demands. Built with SMARTMOS™ Very High Voltage Technology, this IC provides reliable and energy-efficient performance in AC-DC adapters, chargers, and SMPS designs.

Packaged in an SOIC-8 form factor, it operates at a fixed 60kHz switching frequency and integrates a high-voltage startup FET, ensuring efficient and lossless power-on sequences. This current-mode controller enables excellent control over switching behavior, offering pulse-by-pulse protection and audio-susceptibility resilience.

When the power demand decreases, the IC enters skip-cycle mode, optimizing efficiency in standby or light load conditions. It also features an overload protection system with auto-recovery and a thermal shutdown with hysteresis, making it ideal for robust and safe power designs.
