NCP1013AP100G

NCP1013AP100G is ON Semiconductor’s primary-side, off-line switch-mode power-supply controller with an integrated high-voltage MOSFET (GreenSwitch family). It’s designed for flyback converters in low- to medium-power offline supplies (e.g., wall adapters, chargers, LED drivers).
Key points:
- Fixed-frequency, current-mode PWM with an integrated HV DMOS (roughly 650–700 V).
- Valley switching/low switching losses and suitable for compact designs.
- Protections: undervoltage lockout, overcurrent protection, thermal shutdown, and auto-restart (hiccup) on faults.
- Typical operating arena: universal input (≈85–265 VAC), low-to-tens-of-watts output, minimal external parts.
- Package: 8-pin (AP100G code), lead-free variant available.
Note: Exact pinout, startup behavior, and performance depend on the specific design; consult the NCP1013AP100G datasheet for detailed electrical characteristics and application guidelines.

Here are the typical features of NCP1013AP100G (Power Integrations):
- Integrated high-voltage MOSFET for offline flyback operation
- Current-mode PWM control for efficient regulation
- Primary-side regulation (PSR) option to simplify feedback (no optocoupler)
- Wide input AC range with high efficiency across loads
- Low quiescent/standby current
- Protection features: overvoltage, overcurrent (cycle-by-cycle), and thermal shutdown
- Fault modes: hiccup/auto-restart on fault conditions
- Suitable for compact offline SMPS and LED driver applications
- RoHS-compliant and designed for compact, cost-effective power supplies
Note: For exact electrical specs (voltages, currents, timing, packaging), consult the official datasheet.

8-pin device (SO-8). It is an off-line switch-mode power-supply controller with an integrated high-voltage MOSFET, used in flyback adapters. It provides current‑mode PWM control, startup, undervoltage lockout, protection (OC/short-circuit/overload), and primary-side regulation for SMPS.
