Overview
GP8642X is a high-performance AC/DC power control switch designed for chargers and adapters. This IC employs primary-side feedback and control technology, achieving 4% constant voltage/constant current accuracy without optocouplers or TL431. It uses PFM control in constant current mode and a PFM/PWM hybrid control mode in constant voltage mode. The IC integrates output cable compensation, helping reduce switching losses, simplify system EMI design, and optimize output characteristics. In addition, GP8642X provides soft-start, audio noise elimination technology, and multiple protection features, including auto-restart, cycle-by-cycle current limiting, VCC OVP/UVP, pin open/short-circuit protection, and gate clamp protection. The IC is available in an SOP8 package.
Applications
- Adapters and chargers for mobile phones, cordless phones, PDAs, MP3 players, and other portable devices
- LED driver power supplies
- Replacement for linear power supplies and RCC switching power supplies
- Other auxiliary power supplies
Key features
- Primary-side sensing and feedback — no optocoupler or TL431 required
- 4% CC/CV accuracy under normal input conditions
- Integrated output line loss compensation
- Ultra-low standby power, typical 70mW
- Audio noise suppression technology
- Integrated leading-edge blanking
- Cycle-by-cycle current limiting
- VCC OVP and UVP protection
- Open-pin protection
