NCP1060BD060R2G

NCP1060BD060R2G is ON Semiconductor’s integrated high‑voltage switch-mode power supply controller intended for offline isolated flyback converters. It combines a fixed‑frequency, current‑mode PWM controller with an on‑chip high‑voltage MOSFET, simplifying design of offline adapters and compact power supplies.
Key features (typical):
- Integrated high‑voltage MOSFET (around 600 V class)
- Fixed‑frequency current‑mode control
- Startup current limiter, undervoltage lockout, enable input
- Overcurrent/short‑circuit protection and thermal shutdown
- Suited for compact 5–60+ W offline power supplies
Typical applications: offline AC–DC adapters, chargers, and small isolated power supplies.
For exact specifications, pinout, and design guidelines, consult the NCP1060BD060R2G datasheet and ON Semiconductor product page.
