NCP12510CSN65T1G

NCP12510CSN65T1G is ON Semiconductor’s NCP12510 family offline SMPS controller, packaged in CSN65T1G. It is used for flyback converters in low- to medium-power AC-DC adapters and LED driver applications.
Key points:
- High-voltage startup and drive for direct mains operation.
- Current-mode PWM control with built-in protection: UVLO, OVP, OCP, and OTP.
- Soft-start and stable control for reliable, compact power supplies.
- Suitable for primary-side regulation designs (with or without secondary feedback, depending on topology and app note).
Benefits:
- Enables efficient, compact, cost-effective flyback supplies with robust protection.
Packaging:
- CSN65T1G RoHS-compliant package (temperature grade indicated by T1G).
How it works:
- Converts rectified mains to a regulated output by driving a primary-side switch; relies on external components (transformer, feedback network) per application.
Applications:
- AC-DC wall adapters, small power supplies, LED drivers.
Note: For exact electrical specs, pinout, and recommended circuit diagrams, consult the NCP12510 datasheet.

NCP12510CSN65T1G is in a 6‑pin SC‑70 (SOT‑23‑6) package.

- Pin count: 8 pins (8-pin package, e.g., SO-8).
- Function: Off-line flyback switching regulator controller with an integrated high-voltage MOSFET for primary-side regulation in switch-mode power supplies (SMPS); uses current-mode PWM control (often PSR/no optocoupler required).

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation)
- What kind of company: An American multinational semiconductor company that designs, manufactures, and markets energy-efficient electronic components, including power-management ICs, analog, sensors, and other semiconductor products.

- Isolated offline SMPS using flyback topology
- Low- to mid-power wall adapters and chargers (USB/mobile)
- LED constant-current drivers
- Standby/auxiliary supplies for consumer electronics (set-top boxes, TVs, audio)
- General-purpose AC-DC power supplies with primary-side regulation and high efficiency
