NCP1399BA
features a dedicated output to drive the PFC controller. This feature together with dedicated skip mode technique further improves light load efficiency of the whole application. The NCP1399 provides a suite of protection features allowing safe operation in any application. This includes: overload protection, over-current protection to prevent hard switching cycles, brown-out detection, open optocoupler detection, automatic dead-time adjust, overvoltage (OVP) and overtemperature (OTP) protections.
Features
- High-Frequency Operation from 20 k Hz up to 750 k Hz
- Current Mode Control Scheme
- Automatic Dead-time with Maximum Dead-time Clamp
- Dedicated Startup Sequence for Fast Resonant Tank Stabilization
- Skip Mode Operation for Improved Light Load Efficiency
- Off-mode Operation for Extremely Low No-load Consumption
- Latched or Auto-Recovery Overload Protection
